It is feasible to use the waste cracked bricks as coarse aggregate.
Concretes of C30 and C60 were prepared with iron mine tailings as fine aggregate and coarse aggregate and with natural sand and common crushed stone separately.
Study on mechanical properties and durability of the C60 high strength concrete made from gneiss coarse aggregate in bridge
The influence of recycled coarse aggregate replacement rate on properties of concrete with the same slump is discussed in the paper.
angular coarse aggregate
Influences of coarse aggregate on dynamic mechanical behaviors of ultrahigh-performance cementitious composites
The skeleton texture formed by coarse aggregate affects the performance of cement stabilized stone with skeleton dense texture greatly.
By testing, the research on different content of coarse aggregate of asphalt mixture will show different stability in high temperature, will provide some reference for construction in future.
Using cracked brick as coarse aggregate in concrete can reduce pollution and decrease the usage of natural aggregate.
Particle shape, percentage of flat-elongated particles and gradation of coarse aggregate can produce remarkable influence on crushing value.
Because of vast volume of a dam,the coarse aggregate of concrete used for constructing a dam is of large grain size and more grading.
Application of grouting material with coarse aggregate in the projects reinforcement
The paper mainly introduced the application technology of the pumping high strength concrete (C60) which takes crushed gravel as coarse aggregate with big fluidity.
The basic principle is the VCA formed by the coarse aggregate is filled with the fine aggregate, the filling, the asphalt and the preconcerted void content.
coarse aggregate concrete
The strength and modulus of elasticity of matrix increase from almost zero, then at a certain age up to those of the coarse aggregate, and even exceed for lightweight concrete.
Fractal measurement and characterization on roughness of coarse aggregate surface texture
By uses of Handan raw materials, this paper studies the influence of coarse aggregate limiting grain size, water-binder ratio, fly ash replacement, sand-total aggregate ratio on the strength and workability of concrete prepared with low water-binder ratio.
It is very important to determine reasonably the maximum grain size, graded sizes and gradation of the coarse aggregate.
