Ammonium oxalate treatment, previously extensively studied on limestone in the laboratory, was applied to powdering historical stonework (limestone) situated on the shoreline in the Mediterranean Island of Malta. Th...
Limestone fines are increasingly used in cement and concrete for improved material properties and sustainability. This paper presents recent research at Iowa State University on utilization of limestone fines in concr...
This investigation was carried out to study the effect of aggregate roughness on ITZ (interfacial transition zone) at same water/cement ratio and the influence of silica fume on the bond strength. On the experimenta...
In recent years, the need for low energy materials has become increasingly important. With government targets aiming to reduce carbon emissions by 80% by 2050, and the construction industry being responsible for 50% o...
In this paper, concrete with limestone coarse aggregate was studied due to frost action in saline and nonsaline environments. The main focus is to explain the damaging formula of concrete with poor quality of limeston...
Two CaCO3-based materials (limestone and clamshells) and steel slag were used as mineral admixtures in cement to produce ternary blends and their influences on hydration and portlandite formation were analyzed. Addi...
Nowadays, technologies in construction field have offered several kinds of chemical admixtures, which offer different behaviors at the fresh state of the batch and by consequence, it is resulted with different mechani...
Crushed Ghanaian limestone (L) powder was analysed for its physical, chemical and microstructural properties for the formulation of mortar for masonry. Ordinary Portland Cement (OPC) was replaced by 10- 40% limest...
