Anti-freezing cement

Abstract

The invention discloses anti-freezing cement which comprises the following components in parts by weight: 50-70 parts of cement clinker, 3-5 parts of calcium chloride, 1-3 parts of magnesium chloride,3-7 parts of borax, 10-20 parts of bentonite, 5-8 parts of triethanolamine, 5-8 parts of carboxymethyl cellulose sodium and 1-2 parts of an anti-freezing agent. The anti-freezing cement disclosed bythe invention is good in anti-freezing effect, can be used in low-temperature environments in winter, and is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an antifreeze cement. Background technique [0002] In winter, when the outdoor temperature is below zero, the cement will freeze and construction will not be possible. In order to prevent cement from being damaged by freezing at low temperatures, people usually adopt antifreeze methods such as adding antifreeze or steam curing, heat preservation, etc., but the latter is not suitable for large-scale application due to complicated construction and low efficiency. At present, the construction industry mainly uses cement antifreeze to be added to ordinary cement during construction. Although this method has produced certain positive effects, since the antifreeze is generally only a few percent of the weight of cement, there is often uneven mixing. phenomenon, resulting in low antifreeze, uneven antifreeze effect, affecting construction quality, and causing ce...

[0002] In winter, when the outdoor temperature is below zero, the cement will freeze and construction will not be possible

In order to prevent cement from being damaged by freezing at low temperatures, people usually use antifreeze methods such as adding antifreeze or steam curing, heat preservation, etc., but the latter is not suitable for large-scale application due to complicated construction and low efficiency.

At present, the construction industry mainly uses cement antifreeze to be added to ordinary cement during construction. Although this method has produced certain positive effects, since the antifreeze is generally only a few percent of the weight of cement, there is often uneven mixing. Phenomena, resulting in low antifreeze, uneven antifreeze effect, affecting construction quality, and causing certain economic losses. In addition, the addition of antifreeze must be accurately controlled during the construction process, which will bring inconvenience to construction.
