Abstract

The invention discloses a compression-resistant and heat-preserving concrete. The raw materials include: cement, fine aggregate, coarse aggregate, and auxiliary materials; the cement includes aluminate cement and white cinder The cinder compound has a weight ratio of 200‑400:35‑65. The invention improves the thermal insulation performance of concrete, solves the problem of poor concrete thermal insulation that has been plagued for many years, and enhances the toughness and compressive strength of concrete, effectively enhances the mechanical properties of concrete, and makes the concrete quality stable and durable. And reduce the manufacturing cost of commercial concrete, improve the quality of commercial concrete, and further expand the overall competitive advantage.

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a compression-resistant and heat-preserving concrete. Background technique [0002] Concrete, referred to as "concrete (tóng)", refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to cement as cementing material, sand and stone as aggregate; mixed with water (with or without admixtures and admixtures) in a certain proportion, obtained by stirring, molding and curing Cement concrete, also known as ordinary concrete, is widely used in civil engineering. [0003] The existing concrete has poor thermal insulation and poor toughening effect, which seriously affects the service life of the concrete and shortens the service life of the building. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present inv...
