Non-shrink grout price consulting

High-strength non-shrink grout - Product Features 1. early strength, high strength: 1-3 days compressive strength of up 30-50Mpa more. ? 2. The gravity high: to fill all the gaps and meet the requirements of secondary grouting equipment. ? 3 micro-expansion: to ensure close contact between the equipment and infrastructure, non-shrink grout after the second. High bond strength, and bond strength of not less than round 6Mpa. ? 4. Winter Construction: allow for outdoor construction at temperatures of -10 ℃. ? 5. durability: This is inorganic cementing material life more than the life of the concrete foundation. After a million times fatigue test, 50 freeze-thaw cycle experiments no significant changes in intensity. 30 days immersed in the oil intensity has improved significantly. High-strength non-shrink grout - Usage 1. Applicable to the machine base, foundation grouting anchor bolts and other equipment. ? 2. building beams, plates, columns, foundation, floor and road reinforcement, repair, reinforcement. ? 3. Can be anchoring and structural reinforcement and steel anchor bolts. ? 4. subways, tunnels, underground works against the play embedded solid construction joints. ? 5 and secondary grouting steel (rail, steel, steel columns, etc.) and basic fixed connection. High-strength non-shrink grout - a reference to calculate the amount of the reference amount to 2.28 to 2.4 tons / cubic meter basis, calculate the actual usage. ? It is because of the high strength grout, cement can achieve far more than strength, and change the cement shrinkage during curing characteristics, so called high-strength non-shrink grout! ! ? Grout have different models, such as CGM, HGM, etc., which are based on criteria different architectural institute to set, does not mean that the product quality is good or bad, the specific usage needs test.
