Portland cement concrete is one of the most commonly used man-made materials. Its mechanical strength and durability are functions of the various chemical pro-cesses occurring during the mixing and curing pro-cesses . A major factor determining the strength of the concrete is the bond at the interface of the matrix and the aggregates .Life Cycle Assessment of Portland Cement and Concrete ,uptake from crushing and storing of the demolished concrete (scenario 1) such as higher durability and lower maintenance may be theoretically combined with a comparable Portland cement is one of the fundamental components of concrete and mortar.

Portland Cement Dust HSE
In brief, Portland cement is produced by crushing and grinding calcareous materials (e.g. limestone, chalk) and argillaceous materials (e.g. clay, shale), as a wet slurry or in a dry state. The mixture is calcined in a rotary kiln and the resulting clinker is finely ground. The productStormwater Best Management Practices: Concrete Washout,Concrete is a mixture of cement, water, and aggregate material. Portland cement is made by heating a mixture of limestone and . clay containing oxides of calcium, aluminum, silicon and other metals in a kiln and then pulverizing the resulting clinker. The fine aggregate particles are usually sand. Coarse aggregate is generally gravel or crushed
