Problems solved by technology

However, due to the introduction of slag, the hydration process and strength development of the cementitious material system have changed, especially when the slag content is large, the early strength of the system will be significantly reduced and the mechanical properties cannot be achieved.
In addition, due to the introduction of slag, the bonding performance of the cementitious material system will be reduced, and it is easy to be affected by changes in temperature and humidity (such as seasonal changes, sun and rain, weathering), mechanical forces (load-bearing, overload, water impact, etc.) or even Aging phenomena such as freeze-thaw, cracks, melting, carbonization, etc.

Abstract

The invention relates to an anti-aging slag additive which comprises the following components in percentage by mass: 1-3% of diatomite, 0.5-10% of sodium hydroxide, 0.1-0.2% of cross-linking agent, 0-0.5% of quinoline oxide, 5-20% of sulfate, 0-0.8% of calcium oxide, 1-5% of polyurethane waterproofing agent, 0-2% of coalescing agent, 10-40% of compound alcohol solvent and the balance of water. According to the anti-aging slag additive, the polyurethane waterproof agent is added, when the anti-aging slag additive is added into slag, the slag and cement can be cured to form a compact tough film,the compact tough film can be tightly attached to the surfaces of slag foam holes, and the hydrophobicity, the heat preservation performance and the compression resistance of the slag are greatly improved.

Description

technical field [0001] The invention relates to the technical field of slag, in particular to an aging-resistant slag additive. Background technique [0002] Slag is a by-product of blast furnace smelting pig iron, which is an industrial waste slag formed by melting and combining the soil components of iron ore and limestone flux at 1400-1500 °C. Due to its potential hydraulicity, slag can be used as cement mixture and concrete admixture instead of clinker and cement, which has obvious economic and environmental benefits, namely saving energy, reducing CO2 emissions and protecting the environment. At the same time, as a high-quality auxiliary gelling material. However, due to the introduction of slag, the hydration process and strength development of the cementitious material system are changed. Especially when the slag content is large, the early strength of the system will decrease obviously and the mechanical performance index cannot be reached. In addition, due to the ...
