Abstract

The invention discloses a No. 0 colloidal crystal special for shrinkage-free large flow state cement mortar. The colloidal crystal comprises 1 to 4 weight parts of lithium carbonate, 3 to 10 weight parts of polycarboxylic water reducing agent, 4 to 14 weight parts of boric acid, 0.5 to 1 weight part of tartaric acid, 6 to 11 weight parts of calcium sulfoaluminate powder and 67 to 80 weight parts of fly ash. A preparation method for the colloidal crystal comprises the following steps of: (a), stirring; (b), packing; and (c), storing. By adopting a unique proportion, the early strength of the cement mortar is quickly promoted, and the promoting time is 1 to 3 hours; the cement mortar can adapt to special environments such as iron, chromium and the like; the compactness is improved, and pores are reduced; the cement mortar is good in flowability, low in slump degree, micro-expansive and shrinkage-free; and the final compressive strength of the cement mortar is improved from C40 to C55, the low-temperature construction performance of the cement mortar is improved, and the cement mortar can be normally constructed in an environment of 10-15 DEG C below zero.

Description

technical field [0001] The invention relates to the technical field of special additives for cement, in particular to a special 0# colloid crystal and cement mortar for non-shrinking large-flow cement mortar. Background technique [0002] In the prior art, cement is mixed with water to form a slurry, which can firmly bond sand, stone and other materials together. It is a building material and engineering material with the largest amount of use among inorganic non-metallic materials, and is widely used in construction, water conservancy, etc. , road, petroleum, chemical and military engineering. [0003] However, it is difficult for cement mortar to maintain a good flow state in a state of high viscosity, and it is prone to various construction quality problems caused by the habit of adding too much water or improper maintenance during on-site construction. Moreover, the existing cement mortar mixed with additives has a final compressive strength of C40 and can only be const...
