Purpose – The study aims at investigating the optimum proportion of coconut fibre and cement suitable for rammed earth wall construction. Coconut fibres and cement can be easily incorporated into the soil mixture which adds strength and durability to the wall. This paper highlights the salient observations from a systematic investigation on the eff...

Purpose – Industrial wastes such as copper slag and fly ash are being generated in tons every year and disposed mainly by land fillings, resulting in wastage of useful land. Copper slag in itself is a granular cohesionless sand like material while fly ash is highly pozzolanic. In the present paper, copper slag and fly ash mixes with cement as stabi...

Synopsis: This study investigates the effect of recycled coarse aggregate (RCA) as replacement of natural coarse aggregate on the strength properties of concrete. The investigation was carried out by conducting unconfined 14 compressive strength (UCS) test, indirect tensile strength (ITS) test, flexural strength test and bond strength test on five...

Foam characteristics, including density, stability, and texture, influence the properties of end products like foamed concrete. The present work investigates the individual and combined influence of xanthan gum and low-cost sodium-based admixtures (NaOH, NaCl, and Na2CO3) on the viscosity of sodium lauryl sulfate (SLS) foaming solution and the foam...

Affordable housing is a term used to describe dwelling units whose total housing cost are deemed “Affordable” to a group of people within a specified income range. In a building the foundation, walls, doors and windows, floors and roofs are the most important components, which can be analyzed individually based on the needs thus, improving the spee...

Questions

Questions (6)
Question
Please suggest few simple methods for identification rather than characterizing the mix using complicated techniques like NMR. Also, please give your views regarding the production of geopolymer using low-cost waste materials like fly ash, clay, etc, rather than producing from energy intensive metakaolin.
Question
Cement mortar gains strength with time due to chemical reactions involved and formation of C-S-H gel but how bond between aggregate and mortar takes place specifically.
Question
I observed in an experiment that the residual moisture content in samples of soil cement increases as cement content increases. The samples were made at a constant water content (OMC of raw soil) and had the same compactive effort. Samples were tested after same period of curing and drying.
Please provide me any research paper having similar results.
Question
I need to find out the tensile strength of a single fibre or coconut coir using simple methods.
