The mechanized construction of plastering mortar has made a breakthrough in recent years. Plastering mortar has also developed from the traditional site self-mixing to the current common dry-mix mortar and wet-mix mortar. Its performance superiority and stability are the key factors to promote th...Read more »

As soon as the cement-based material added with latex powder contacts water, the hydration reaction begins, and the calcium hydroxide solution quickly reaches saturation and crystals are precipitated, and at the same time, ettringite crystals and calcium silicate hydrate gels are formed. The soli...Read more »
