A concrete external curing agent

Abstract

The invention discloses a concrete external curing agent, which belongs to the technical field of building materials. The external curing agent for concrete developed by the present invention is mainly composed of β-sitosterol, phospholipid, water, vegetable oil, drying oil, polyallylamine, defoamer and calcium bicarbonate, and after first stirring and mixing the β-sitosterol and phospholipid , pour into the preheated vegetable oil, then add dry oil to obtain an oil phase; stir and mix water and polyallylamine, then add calcium bicarbonate, preheat to obtain a water phase; Add the oil phase to the water phase. After the oil phase is added, add the defoamer, continue stirring and mixing at a constant temperature for 40-60 minutes, discharge, and fill to obtain the concrete external curing agent. The product developed by the invention has good storage stability, can significantly improve the performance of the concrete after curing, and does not cause secondary pollution to the environment after use.

Description

technical field

[0001] The invention discloses a concrete external curing agent, which belongs to the technical field of building materials. Background technique

[0002] Concrete is one of the most widely used building materials in construction projects. Its performance depends not only on the composition and ratio of raw materials, but also on later maintenance. If the concrete is not maintained in time after construction, its internal moisture will pass through the system. The capillary pores evaporate to the outside world, resulting in insufficient hydration of the cementitious material and reduction of hydration products, which in turn causes the performance of concrete to decline. Therefore, curing is crucial to the development of concrete properties and must be taken seriously.

[0003] Traditional concrete curing methods mainly include water curing, steam curing, landfill curing and plastic film covering, etc. This kind of curing method is time-consuming, laborious,...
