Water-preserving agent for cement

Abstract

A water-preserving agent for cement contains proportionally hydroxyethyl cellulose ether, dispersable latex powder and high-hydroscopicity resin. It is applied through dissolving it in water, laying aside for 10 min, and mixing the solution with cement. Its advantage is high effect to preserve water and increase the strength and durability of concrete.

Description

technical field [0001] The invention relates to a water-retaining agent, especially a cement water-retaining agent. Background technique [0002] Cement needs enough water to react with it in the hardening process to ensure the strength of the cement. It is generally required that the freshly finished concrete needs to be watered and cured for more than 7 days. However, in many practical projects, it is often impossible to do watering and curing for 7 days, and the water on the surface of the cement evaporates relatively quickly. If the water in the concrete is not retained, the strength of the cement will inevitably be affected. The traditional method of concrete water retention is to add an appropriate amount of cellulose. Cellulose has a certain water retention effect, but the effect is not good. Especially for thin layer cement, the water retention effect of cellulose is not ideal. At present, there are also curing agents that play a role in water retention on the ma...
