This study illustrates the effect of incorporating natural pozzolan (NP) and silica fume (SF) in cement-based mortars on the compressive strength. Up to 40% of the weight of cement in cement mortars can be replaced by NP powder. NP in its natural state can be used to replace up to 40% of the volume of sand in cement mortars. The replacement levels...

The effects of polypropylene fibres on mortar and cement-paste cracking were investigated using different amounts of fibre fractions and eccentric rings under restrained-shrinkage conditions. Eccentric-ring tests were conducted to investigate early-age shrinkage cracks. The characteristics of restricted cementitious materials were described by eval...

This paper proposes an eccentric ring test that can be used to determine the behaviour of restrained cement materials with regard to cracking time and select concrete mixtures that are less likely to crack. The effects of polypropylene fibres on the cracking of cementitious composites were investigated using three volume fractions of the fibres and...

Drying shrinkage can be defined as the reduction of volume that concrete undergoes as a result of the moisture relocation when exposed to a lower relative moist surrounding environment than the foremost one of its basic pore structure system. Finite element model(FEM) is developed and implemented, to simulate and analyses the early age restrained c...

Crack potential and hydration processes of the cement pastes were monitored using an up-to-date eccentric steel cracking frame (ESCF), associated with the non-contact electrical resistivity apparatus, independently. The objective of employing the ESCF is to give a new method determining cracks of concrete at early age. The findings indicate that th...
