Abstract. Rock wool and slag wool pertain to the same kind of thermal insulation material, which
can be produced in quantity and widely used, by comparison with other inorganic fiber thermal
insulation materials, thus it is one of the most important thermal insulation material for the national
economic development in our country. After the implementation of Civil Construction Energy
Efficiency Management Regulation, it puts forward higher requirements for the energy saving
standard of new buildings, thus the application prospect of rock-mineral wool thermal insulation
material is promising. This paper mainly presents the source of rock-mineral wool, its main relative
merits as well as its application in the construction field, moreover, the application and development
potential of rock-mineral wool as the thermal insulation material for building wall construction.
Introduction
Civil Construction Energy Efficiency Management Regulation has been put into effect since the
first day of January in 2006, in which the construction of new buildings should be strictly
accordance with the design standard of energy saving 50％, a number of large cities including
Beijing, Tianjin and Shanghai take the lead in implementing the standard of energy saving 65％. In
order to achieve the energy saving standard above, however, the standard can be hardly realized
merely by the self-thermal insulation of wall construction materials, thus a variety of thermal
insulation materials have been widely applied in the wall thermal insulation system. Some organic
thermal insulation materials such as EPS and XPS have been mainly used for the wall thermal
insulation system in our country, nevertheless, rock wool has been increasingly used as a kind of
thermal insulation material for the wall thermal insulation system in many public projects and
high-end housing construction, by virtues of its favorable fireproof performance, air permeability
and excellent sound insulation property.
Source of materials
Rock wool and slag wool pertain to the same kind of thermal insulation material, which can be
produced in quantity and widely used, by comparison with other inorganic fiber thermal insulation
materials, thus it is one of the most important thermal insulation material for the national economic
development in China. Rock wool and slag wool are distinguished based on the source of materials.
The main materials of rock wool include basalt, dolerite, dolomite and the like, which are made into
inorganic fiber materials by means of melting in high temperature, blowing or centrifugation, etc;
while slag wool is made from industrial solid waste (mainly blast furnace slag, copper slag or

... Effective insulation systems are vital in modern industry for minimizing energy loss and ensuring the stable operation of pipelines and process equipment, particularly in high-temperature sectors such as chemical processing [1], oil refining [2], and power generation [3]. Among the wide array of insulation materials, rock wool stands out due to its excellent thermal insulation properties, high melting point, and intrinsic fire resistance [4]. Rock wool is primarily made of basaltic rock and recycled industrial slag, produced by melting these raw materials at over 1400 • C and rapidly spinning the molten material into fine fibers, resulting in a highly porous, interwoven structure [5]. ...
Simulation of Internal Environmental Conditions Within Rock Wool Insulation: Implications for Corrosion Under Insulation in Piping Systems

  • May 2025
Rock wool is widely used in industrial piping systems for its excellent thermal insulation properties, but its porous structure allows water infiltration that can lead to corrosion under insulation (CUI) on metal pipe surfaces. In order to investigate how water infiltration into the insulated pipeline system creates a corrosive environment, a study on the flow behavior of fluids in porous media was conducted. Experiments were performed to measure the flow velocity and pressure drop along three principal directions—axial, radial, and circumferential. These measurements enabled the derivation of specific viscous and inertial resistance coefficients, which characterize the flow through the rock wool structure. The results indicated that the flow parameters of rock wool change over time and with repeated use, particularly after dry–wet cycles. The experimentally derived parameters were incorporated into both small-scale and large-scale three-dimensional computational fluid dynamics (CFD) models to simulate water transport within the rock wool insulation layer. Validation experiments performed on a real rock wool-insulated pipeline system confirmed the predictive accuracy of the CFD simulations in capturing water movement through the insulation. The large-scale model further analyzed the influence of inlet velocity, rock wool aging, and pipeline inclination on the development of environmental conditions for CUI.

... Heat insulators [28] based on foamed polyurethane, polypropylene, polystyrene, etc., are combustible [29,30], and their use for the construction of residential buildings and technological structures carries certain risks in terms of fire and chemical hazards. The fibrous heat-insulating mineral materials (mineral and glass wool) do not provide full protection of metal structures against corrosion, as such constructions require additional waterproofing [31]. Porous heat-insulating cement-containing materials, as well as concretes with artificial porous aggregates are less effective than polymers, because their thermal conductivity coefficient reaches 0.7 W/K·m [32,33], and the required thickness of the heat-insulating layer and the total weight of the product become significant. ...
Formation of Cellular Concrete Structures Based on Waste Glass and Liquid Glass

  • Dec 2023
The use of waste in the production of building materials is one of the possible ways to solve problems related to the sustainable management of non-degradable waste and difficult-to-recycle secondary resources. In this paper, a method is proposed for the non-autoclave production of an ultra-lightweight cellular concrete based on Portland cement, glass waste and liquid glass. A mixture of sodium hexafluorosilicate and hydroxide is used as a hardening activator, an aluminum powder serves as a gas-forming agent. The setting and hardening of raw mixtures occurs under the action of exothermal heat release due to a complex of chemical reactions occurring in the system, and the resulting material does not require additional heat treatment. It is optimal to use two fractions of glass waste to achieve acceptable material strength: coarse crushed (fineness modulus Fm = 0.945) and finely ground (specific surface Ssp = 450–550 m2/kg) glass. Glass particles of the fine fraction of glass, along with Portland cement, participate in hydrolytic and structure-forming processes, while glass particles of the coarse fraction play the role of reinforcing filler. The influence of the dispersion of glass and the density of liquid glass on the density, porosity, strength, water absorption and water resistance of the resulting cellular material was determined. At an average density of cellular concrete in the dry state of 150–320 kg/m3, the following characteristics can be achieved: a compressive strength up to 2.0 MPa, bending strength up to 0.38 MPa, thermal conductivity coefficient of the material in the range 0.05–0.09 W/(K·m), and a maximum operating temperature of 800 °C. The proposed ultra-lightweight cellular concrete can be used as a non-combustible heat and sound insulation material, as well as a repairing composition; the cellular concrete blocks can be used as filling masonry and for the construction of non-bearing internal walls.

... Compared to other types of inorganic fiber insulation, rock wool is a vital thermal insulation element in India due to its capacity to be produced in large quantities and widespread application. [24]. Fibrous materials trap air within their fibers, which in turn reduces convective heat transfer and limits gaseous heat conduction by lowering gas-molecule collisions. ...

Rock wool is a man-made fiber produced by melting inorganic stones such as basalt, diabase, dolomite obtained from volcanic rocks, and it is an environment friendly resource and generally used for building insulation. Rock wool has good thermal resistance and insulation properties. In this study, PLA/Rock wool biocomposites with 20-30-40% rock wool support were produced with twin-screw extruder and then press molded. Tensile and flexural tests were applied to reveal mechanical properties of composites. FT-IR spectroscopy was used for investigation of chemical changes. TGA /DTG analysis were carried out to determine thermogravimetric properties of biocomposites, where thermal conductivity was measured to investigate heat transfer characteristics. The results showed that flexural strength of composites decreased 5-40% with increasing ratio of rock wool (20-40%), while tensile strength decreased 40-60% with increasing amount of rock wool (20-40%). Besides that, rock wool accelerated thermal degradation of PLA, but the composites have 25% better heat insulation property than neat PLA.

  • May 2019
The performance of a thermally insulating material is mainly determined by its thermal conductivity, which depends on the density of the material , porosity, moisture content and average temperature difference. This paper presents the results of experimental studies of the coefficient of thermal conductivity of mineral wool, polyisocyanurate foam, aerogel and carbon in a stationary thermal regime. Thermal insulation indicators of insulation are determined on a flat sample using the device PIT 2.1. The results should be of great importance for manufacturers of materials, building owners and designers when choosing suitable insulation materials and correctly predicting the thermal and energy performance of buildings and their energy efficiency.

Crystal-pit-cracking formation on composite modified slag fiber in long-term water immersion
Article
  • Dec 2019
  • J NON-CRYST SOLIDS
Composite modified slag fiber (CMSF) has been widely used as insulation material for enclosures in the field of construction; however, its corrosion characteristics and crack formation are unclear. Therefore, the damage behavior of CMSFs with two acidity coefficients (ACs) immersed in water for 365 days was studied; the fiber structure and composition were measured. The crystalline phase on the fiber surface was identified as CaCO3 deposits that dissolved after long-term immersion, resulting in pits. Owing to continuous replacement of H⁺, Ca²⁺ continuously migrates from the inside to the outside of the fiber, resulting in a stepwise increase in the AC of the fiber cross-section; the surface pits significantly increased and joined together to form an axial crack. However, the Si-O-Si bond has no significant fracture during long-term immersion. These findings support the theory on the crack behavior of CMSFs during long-term immersion for practical applications.
