Portland Cement Concrete Mix Ratio

It meets the standard ASTM specification for Portland cement Suitable for laying bricks setting blocks patching stone work and a variety of other uses Compatible with applications requiring type III Portland cement Mixing ratio for concrete is 1 part cement 2 parts sand and 3 parts gravel

A standard ratio for mixing concrete from raw materials is 1 part Portland to 2 parts concrete sand to 3 parts gravel by VOLUME For example one 926 lb bag of QUIKRETEreg Portland cement 167 pounds of concrete sand and 295 pounds of gravel will yield approximately 41 cubic feet of concrete

Concrete Mix Ratio for a C20 and C20P Portland Mix The proportions of materials for a C20 and C20P P Portland cement concrete mix are 1 part cement 2 parts fine aggregate sand

A standard ratio for mixing concrete from raw materials is 1 part Portland to 2 parts concrete sand to 3 parts gravel by VOLUME A cubic yard 27 cubic feet of concrete will require approximately 600 pounds of Portland 612 bags 926 lb each of QUIKRETEreg Portland Cement 1085 pounds concrete sand and 1915 pounds gravel

Ingredient Ratio A good general purpose concrete mix combines one part Portland cement 25 parts sand three parts gravel and 05 parts clean water For more strength and water resistance reduce the sand to two parts Mix dry ingredients well then add
