Problems solved by technology

However, waterproof coiled materials and coatings will age, and their waterproof life is only 20 to 30 years at most, which is out of sync with the life of concrete (70 to 100 years), so this method is inefficient and does not cure the symptoms
And a high-efficiency inorganic waterproof and moisture-proof agent (liquid) formulated by more than 20 kinds of chemical materials such as potassium permanganate and sodium carbonate and rare materials, although its waterproof and moisture-proof effect is obvious, but this inorganic waterproof and moisture-proof agent is harmful

Abstract

The invention discloses a high-impervious microcrystal self-curing type cement additive, which relates to the filed of concrete additive and can be used for preparing high-impervious motar or microaggregate concrete by being mixed with cement. The high-impervious microcrystal self-curing type cement additive comprises the following components in percentage by weight: 30-50% of active silicon oxide, 32-55% of levigated mineral powder or coal ash or quartziferous silicon epitaxy materials or limestone powder, 5-8% of phosphate and 7-11% of water reducer. The additive of the invention can be used for preparing high-impervious flaw self-curing type motar or the microaggregate concrete by being mixed with cement.

Description

technical field [0001] The invention relates to a high-impermeability microcrystalline self-healing cement admixture, in particular to an inorganic active admixture that is mixed with cement to prepare high-impermeability mortar or micro-aggregate concrete to have high impermeability and crack self-healing properties. agent. Background technique [0002] Cement concrete or mortar is the main material of buildings. The inherent defect of the concrete material is that it is brittle, and micro-cracks and local damage will inevitably occur under the influence of the use process and the surrounding environment. If these damaged parts cannot be repaired in time, it will not only affect the normal performance of the structure and shorten the service life, but also may cause macroscopic cracks and brittle fractures, causing irreparable economic losses to the society. In addition, cement concrete material is a multi-component porous system. The existence and connectivity of pores m...
