Concrete reinforcing agent

Abstract

The invention discloses a concrete reinforcing agent which comprises, by weight, 10 parts of special clinkers, 20-30 parts of industrious solid rubbish, 30 parts of gypsum, 30-40 parts of natural mineral materials and internal maintenance continuous activators, and the internal maintenance continuous activator account for 5% of the total weight of the concrete reinforcing agent. A preparation method of the special clinkers includes the steps: grinding phosphogypsum, furnace clinkers granulated furnace phosphorus slag, granulated furnace phosphorus slag and limestone; mixing grinded materials;adding water and granulating mixture; drying the granulated materials; calcining the materials; cooling the materials; rapidly cooling and crushing the materials to obtain the special clinkers. Steelslag and granulated furnace phosphorus slag are mixed to form the industrious solid rubbish, solid sulfur ash is sufficiently soaked into acrylamide solution, mixture is extracted and filtered at negative pressure and then treated until a saturated surface dry state is achieved to obtain the internal maintenance continuous activators, and the natural mineral materials are alum stone powder. The reinforcing agent can replace 10-15% of cement amount, cost is reduced, compressive strength, penetration resistance and the like are optimized, and reuse of various solid rubbishes is promoted.

Description

technical field [0001] The invention belongs to the technical field of concrete preparation, in particular to a concrete reinforcing agent. Background technique [0002] Concrete is one of the most important civil engineering materials in modern times. It is a kind of artificial stone made of cement, admixture, granular aggregate (coarse / fine aggregate), water, and necessary admixtures according to a certain proportion, mixing, molding, curing and hardening. Among them, the quality of cement and admixtures, the water-cement ratio of concrete, the quality of aggregates, curing conditions (temperature and humidity), construction quality and other factors will all have an impact on the strength and performance of concrete, but in the final analysis the greatest impact is still from the glue. Cementation of gelatinous materials. [0003] Cement is the largest branch of building materials and consumes a lot of raw materials and fuels every year. Practice has proved that the tr...
