Abstract

The invention discloses C80 concrete prepared from stone chips, the preparation materials of the concrete comprise a cementing material, coarse aggregate, a water reducing agent, water and high-calcium stone chips, the dosage of the cementing material is 580-600kg / m < 3 >, and the water-binder ratio is 0.22-0.26. The C80 concrete has the beneficial effects that the stone chips with the average particle size of less than 4.75 mm are adopted, and stone powder contained in the stone chips can fill cement particle gaps; the gel compactness is improved, the surface energy is relatively low, the dispersion is easy, and the water requirement for achieving the same liquidity is low; the problem of lack of high-quality fly ash can be solved by blending ultrafine stone powder in the stone chips andslag powder to prepare high-performance concrete; river sand is replaced with the stone chips of mine production stone to serve as fine aggregate, the problem that no high-quality river sand is used for preparing high-strength concrete in mountainous areas is solved, environmental protection and sustainable development of building materials are facilitated, and huge economic benefits are achieved.

Description

technical field

[0001] The invention belongs to the field of building materials, in particular to C80 concrete prepared from waste stone chips. Background technique

[0002] Concrete is the most widely used building material and plays a pivotal role in construction projects. With the advancement of concrete technology, high-performance concrete with low water-binder ratio, low cement consumption, and low water consumption per unit volume as the main technical features is being constructed on the basis of high-performance water-reducing agents and large-volume mineral admixtures. The application in engineering is more and more extensive.

[0003] Natural sand is generally used as fine aggregate for concrete preparation, but at present, the production of high-quality natural river sand that can be used for high-performance concrete in my country is seriously insufficient, and the distribution of production areas is uneven. In addition, my country's current environmental prote...
