Used as rapid setting agent, lubricant and early strength agent for cement. Used in building mortar and various concretes to speed up the hardening of cement and shorten the setting time, especially during winter construction to avoid too slow setting at low temperatures. Demoulding is quick, allowing the cement to increase strength and be put into use as soon as possible. Calcium formate uses: various dry mixed mortars, various concretes, wear-resistant materials, flooring industry, feed industry, tanning.
It is about to enter a state of low temperature. Calcium formate is a good partner of mortar and can be used for construction at negative temperatures of minus five degrees. It is used in construction to increase the early strength.
Early strength agent is a composite of special early strength materials, modified naphthalene series water-reducing materials and pumping materials. It is a new generation of concrete super early strength The technical indicators of water reducing agent are at the international excellent level. The outstanding characteristics are fast early strength, high water reduction rate, and pumpability. It can be configured to produce commercial concrete that does not bleed, does not segregate, and has good pumpability.
1. Main technical performance
1. Early strength: can significantly improve the strength of concrete Early strength, the 24-hour strength can reach more than 90% of the design strength, the 24-hour compressive strength ratio is 254%, the 36-hour strength can reach more than 100% of the design strength, and the later strength is significantly improved, and the 28-day strength can reach the design More than 120% of the strength can greatly shorten the construction period.
2. Water reduction: It has good water reduction performance, the water reduction rate can reach more than 20%, and the slump of blank concrete can be increased by more than 10cm. Therefore, the water-cement ratio of concrete can be reduced and concrete shrinkage can be reduced. While maintaining the slump and strength of concrete, about 10% of cement can be saved.
3. Plastic retention: It has good pumpability and plastic retention. It can maintain the fluidity of concrete and reduce slump loss. The slump loss in 1 hour is about 1~2cm.
4. Rust resistance: Contains rust resistance Rust component can prevent steel bars from rusting.
2. Scope of application
1. Especially suitable for concrete projects and prefabrication with urgent construction schedules Production and construction of concrete components.
2. Suitable for pumping and non-pumping construction of ordinary concrete and prestressed reinforced concrete. It has good applicability to ordinary Portland cement and slag Portland cement.
3. Can be used in various civil engineering, construction, transportation, water conservancy and other engineering fields.
4. Suitable for construction in seasons with temperatures above -15°C.
