احصل على السعرCompressive strength of Concrete and its importance: As we all know that concrete is a mixture of sand, cement, and aggregate . The strength of the concrete depends upon many factors like individual compressive strength of its constituents (Cement, Sand, aggregate), quality of materials used, air entrainment mix proportions, water cement ratio, curing methods and temperature effects.

احصل على السعرSteel fiber reinforced self compacting concrete is a promising alternative material to traditional reinforced concrete. Contrary to the traditional concrete, the self compacting concrete flows and fills the formwork without the need of vibration or any other type of agitation. Self compacting concrete therefore significantly simplifies the casting process and reduces health risks induced
