How much polypropylene fibers should be added to the special fibers for cement concrete? Polypropylene fibers can play their role in concrete, which largely depends on the number and uniform distribution of fiber monofilaments in concrete. As the surface of the fibers is covered with a special fi...
英语翻译Concrete is a man-made material created by the proper mixing of coarse aggregate,such as gravel ,fine aggregate ,such as sand ,and cement ,with adequate and controlled amounts of water.Concrete is very strong in compression,and ultimate s
The present study is an experimental study in which different concrete samples with different amounts of polypropylene fibers and different cement content are exposed once at a normal temperature of 25 °C and again at high temperatures, including 250 °C and 500 °C. The effect of ...

with calcium carbonate, by a new eco-cement. This new cement, made with magnesium carbonate, absorbs large amounts of carbon dioxide when exposed to the atmosphere. Therefore, using eco-cement for new concrete building projects will significantly help reduce atmospheric concentrations of carbon ...
Low amount of cementStrength performanceManufactured-sandCompared with natural sand, manufactured-sand is of small porosity, poor grain shape and graded, which impacts mixes workability and the properties after hardening. In Concrete, playing the role of retaining moisture water is mainly powder, ...
aThe grading of the coarse aggregate shall be such that when the coarse aggregate is combined with the approved fine aggregate and cement it shall produce a w口rkable concrete of maximum density. Concrete mixes shall be designed to use the largest size and maximum amount of coarse aggregate pra...
