21. Stresses. thermal expansion and contraction of the concrete The structural design of a concrete floor slab on grade is primarily controlled by the stresses caused by moving live loads and in some cases the stationary loads. Stresses in floor slabs on grade resulting from vehicular loads are a function of floor slab thickness, vehicle weight and weight
Sep 16, 2014· Generally, to construct a rubble foundation, the materials required are rubble, cement, sand, and water. Mixing of cement and sand mortar ratio can be changed depending on the strength should obtain but the most frequently used ratio is 1:5 (cement:sand) mix, which we are going to .
2. Firing the cement clinker consumes large volumes of fossil fuels and releases great amounts of carbon dioxide. The International Energy Agency estimates that the increased use of lowclinker cements with a higher content of filler materials such as slag sand and fly ash could reduce these emissions by around 13 percent.
erties of concrete under given job conditions are governed by the quantity of mixing water used per unit of cement or cementing materials (Abrams 1918). The strength of the cementitious paste binder in concrete depends on the quality and quantity of the reacting paste components and on the degree to which the hydration reaction has progressed.
Aug 30, 2012· Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand clay fulfill the need of silicon, iron and aluminum.
