Problems solved by technology

[0012] However, the main component interface agent of the cement curing agent in the above scheme is organic matter, generally made of vinyl acetate-ethylene, which is not conducive to environmental protection; the main mineral composition of Portland cement is: tricalcium silicate, dicalcium silicate, aluminate Tricalcium, tetracalcium aluminoferrite
Tricalcium silicate determines the strength of Portland cement within four weeks; dicalcium silicate exerts its strength after four weeks, and reaches the strength of tricalcium silicate in about one year; the strength of tricalcium aluminate It develops faster, but its strength is low, and it plays a certain role in the strength of Portland cement within 1 to 3 days or a little longer; The strength contribution of salt cement is small

Embodiment 1

[0049] A special curing agent for indoor cement floor, which contains sodium silicate, lithium silicate, magnesium fluorosilicate hexahydrate and isoparaffin, in the form of white dry powder.

[0050] Its specific formula is 200 parts of sodium silicate, 114 parts of lithium silicate, 28 parts of magnesium fluorosilicate hexahydrate, and 3 parts of isoparaffin.

[0051] Among them, magnesium fluorosilicate hexahydrate (mass fraction ≥ 75%) is produced by ourselves. The reaction steps are as follows. Fluorosilicate is produced by heating and reacting fluorite powder, silica sand and concentrated sulfuric acid. The main components in fluorite powder are calcium fluoride and The main component of silica sand, silicon dioxide, reacts with concentrated sulfuric acid to produce hydrogen fluoride and silicon tetrafluoride, the raw materials for the preparation of fluosilicic acid. The main reaction is

[0053] Calcium sulfate is slightly soluble in water and will form pre...

Embodiment 2

[0060] A special curing agent for indoor cement floor, the difference between embodiment two and embodiment one is that 84 parts of lithium silicate are added in its specific formula.

Embodiment 3

[0062] A special curing agent for indoor cement floor, the difference between embodiment three and embodiment one is that 150 parts of sodium silicate are added in its specific formula.

Abstract

The invention discloses a special curing agent for indoor cement floors and a method for using the same, aiming to solve the problem that the general cement curing agent is not suitable for different floors with different active components and the reaction is not sufficient. Its technical points are: the special curing agent for indoor cement floor is dry powder, which contains sodium silicate, lithium silicate, magnesium fluorosilicate hexahydrate and isoparaffin. The special curing agent for indoor cement floor is dry powder, without adding water, just add water according to a certain proportion before use, it is easier and flexible to adjust the ratio of each formula according to the ground conditions; dry powder is relatively high quality Lighter, easy to carry and handle, easy to seal during transportation, and not easy to spill; dry powder indoor cement floor special curing agent has a longer shelf life, and coordination and other reactions between various components are not easy to occur.

Description

technical field [0001] The invention relates to the field of building construction, more specifically, it relates to a special curing agent for indoor cement floor and a preparation method thereof. Background technique [0002] After the cement floor has been used for a period of time, the ground will appear sanding and dusting to varying degrees, and an alkali aggregate reaction (ASR) will occur, that is, when the content of alkaline oxides in the cement is high, it will react with the aggregate contained in the aggregate. Silica undergoes a chemical reaction and forms an alkali-silicic acid gel on the surface of the aggregate. The reaction mechanism is [0003] Na + (K + )+SiO 2 +OH - →Na(K)-SiO 2 -Hgel [0004] When the volume of the alkali silicate gel after water absorption is larger than the solid volume before the reaction, the volume can increase by more than 3 times at the maximum, and the accumulation and expansion of a large amount of gel in the interface ar...
