Crushed stones have edges and corners, rough surface, and good bonding with cement, while pebbles are mostly round, with smooth surface, and poor bonding with cement. When the amount of cement and water are the same, the concrete mixed with crushed stones will The fluidity is poor, but the strength is high, and the concrete mixed with pebbles has goo

Abstract
The invention relates to a concrete processing method and device for engineering construction. The concrete processing method and device for engineering construction comprise the following steps that S1, mountain sand with the size of 0.3-0.6 mm and mountain sand with the size of 0.8-1.18 mm are screened out to serve as fine aggregate, and pebbles with the size of 5-9.5 mm are screened out to serve as coarse aggregate; and S2, the gravel coarse aggregate screened out in S1 is put into a polishing mechanism to be subjected to surface roughening primary treatment. According to the concrete processing method and device for engineering construction, round and full pebble surfaces can be subjected to roughening treatment for multiple times, dry ice particles and ice particles are adopted for conducting cleaning type polishing treatment on the pebble surfaces in the multiple stirring processes, a certain roughening effect can be achieved while the pebble surfaces are cleaned, and secondary filtering is not needed. Wherein the ice particles permeate into gaps of the pebbles after being melted, so that the pebbles reach a saturated surface dry state, the treated pebbles are mixed with other materials to form the concrete with high flowability and high strength after solidification, and the use effect is relatively good.
Description
technical field [0001] The invention belongs to the technical field of concrete processing, and in particular relates to a concrete processing method and device for engineering construction. Background technique [0002] Existing ordinary concrete refers to cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, densely formed and cured and hardened artificial stone. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. The strength grade of concrete is divided by the standard value of cubic compressive strength. The strength grade of ordinary concrete in China is divided into 14 grades: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80 . [0003] In concrete,...
