Study On Compressive Strength Of Gravel Reactive Powder Concrete

A present, the reactive powder concrete (RPC) has become a new research focus in the international field of materials engineering. As a new type of cement-based composite materials, RPC has high strength, high toughness, high durability, good economic performance and environmental performance characteristics. Its mechanical properties are better than the ordinary concrete and high-strength concrete. However, traditional RPC material has a lot of inconvenience in the construction and maintenance. Besides, its cost is very high. Its application is very limited for these disadvantages, In this dissertation, the traditional RPC material is optimized to lower the cost of RPC material and improve its performance of construction. Its compressive mechanical properties are tested.According to tests, this dissertation study on 16 group gravel RPC. We obtained cube compressive strength, axial compressive strength, prism specimens of static compression modulus, prism specimens Poisson's ratio and compressive peak strain of the main performance parameters, these parameters were analyzed and obtained the compressive property of the basic law of gravel RPC.In order to demonstrate the superiority of gravel RPC, we compared with ordinary concrete. Analysis the main compression performance of this materials and fitted out the formula of prism strength and cube strength, peak strain and the prism strength and elastic modulus and cube strength of gravel RPC by software. Provide a reference to latter study on the gravel RPC material. Finally, through a comprehensive analysis of compressive mechanical properties of gravel RPC materials, proposed the optimal mix from the 16 groups of test.
