Abstract
The invention provides a nano-reinforcing agent for sodium sulfate and sodium carbonate alkali-activated gelling materials and its preparation method and application. In terms of parts, it is mainly prepared from the following components through wet grinding process: granulated blast furnace slag powder: 20-35 parts, ion solubilizer: 0.5-2 parts, surfactant: 0.1-0.5 parts, stabilizer: 0.1-0.5 parts parts, and the balance is water. The nano-reinforcing agent used in the sodium sulfate and sodium carbonate alkali-excited gelling materials of the present invention can improve the pore structure of the sample system and have the effect of inducing nucleation, so that the early strength of the sample is improved. When its dosage is 1%-5%, the strength of sodium sulfate and sodium carbonate alkali-activated cementitious material mortar can be increased by 15%-200% in one day, and the strength will not shrink after 28 days, which has great application in the building material industry value.
Description
technical field [0001] The invention relates to the technical field of cement concrete admixtures, in particular to a nano-enhancer for sodium sulfate and sodium carbonate alkali-activated gelling materials, a preparation method and application thereof. Background technique [0002] The residue after ore dressing or smelting is called slag, which is a typical solid industrial waste. Granulated blast furnace slag is a widely used industrial by-product. Pozzolanic activity and potential hydraulic hardness can be used as auxiliary cementitious materials. As we all know, the cement industry has serious energy consumption, natural resource consumption and waste discharge problems. When producing one ton of cement clinker, not only will a large amount of carbon dioxide and other greenhouse gases be emitted, but also a large amount of energy will be consumed to maintain a continuous high temperature environment. Therefore, the sustainable development of the cement industry is fac...
