Abstract

The invention discloses a concrete material containing an active additive. The concrete material comprises Portland cement, the active additive, sodium silicate, quartz sand and water, wherein the active additive comprises material A, material B and material C; the material A is made with allophane and potassium carbonate; the material B is made with tartaric acid, maleic acid, ammonium formate, calcium metaaluminate, oxalic acid, sodium tartrate and calcium chloride; the material C is made with sodium silicate, sodium citrate, zinc formate, calcium carbonate, potassium carbonate, sodium acetate trihydrate, calcium formate, calcium metaaluminate and calcium chloride. The problem that traditional concrete material has insufficient overall mechanical strength and anti-permeability performance is solved.

Description

technical field [0001] The invention relates to the field of concrete materials, in particular to a concrete material containing active additives. Background technique [0002] The waterproof material is the building envelope to prevent the penetration of rainwater, snow water and groundwater; to prevent the erosion of moisture, steam and other harmful gases and liquids in the air; the separation structure to prevent the seepage of water supply and drainage. These materials that prevent penetration, leakage and erosion are collectively referred to. For example, the invention with the patent number CN2017100474779 discloses a cement-based osmotic crystalline waterproofing agent, including components represented by the following parts by weight: 570-630 parts of Portland cement; 275-325 parts of quartz sand; 95 parts of fly ash -105 parts; 2-17 parts of water reducing agent; 80-95 parts of osmotic crystallization masterbatch; osmotic crystallization masterbatch includes sodiu...
