Abstract

The invention provides a formula of ultra-high performance concrete containing coarse aggregate and a low-cost design method. The design method is to pre-set the content of mineral powder, quartz sand and coarse aggregate according to the raw material formula range, measure the porosity of the mixture of the three, and use this as a guide to gradually optimize the content of cementitious materials, and finally obtain different low-cost ultra-high performance concrete formulations with compressive strengths of this grade. The present invention also determines the optimal aggregate size interval through the experiment, and within the interval set by the present invention, it is helpful to obtain ultra-high performance concrete with better comprehensive performance. The orientation of the present invention is simple and scientific, and it can be used to prepare multi-grade UHPC with relatively low cost but still has strong durability of UHPC. waste problem.

Description

Coarse aggregate-containing ultra-high performance concrete formulation and low-cost design method technical field The present invention relates to concrete preparation technical field, relate in particular to a kind of ultra high performance concrete formula containing coarse aggregate and Low cost design method. Background technique [0002] Ultra-high performance concrete (UHPC) was invented in the 1970s and began to be used in the 1990s. to a wide range of research and applications. Ultra-high performance concrete is widely used due to its much higher compressive strength and durability than ordinary concrete. It has a wide range of application prospects, and because of its excellent flexural and tensile strength, UHPC has the ability to partially replace steel. muscle potential. Compared with ordinary concrete, UHPC has utilized the principle of close packing, and the particles of different particle diameters are used in the best ratio. Combined together to a...
