1) Polycarboxylate SJC small dosage, high water reduction in concrete, ready-mixed mortar admixture Fujian, the best content of 0.9% -1.1% by weight of cementitious material. 2) were mixed with concrete mix workability of the two types of poly-carboxylic acid and naphthalene based superplasticizer significantly different. Through the observation of workability and appearance, mixed with concrete without bleeding phenomenon polycarboxylic acid-based admixtures, concrete testing air content of about 4.1%, ready-mixed mortar admixtures, apparent microscopic bubble, concrete has a good cohesiveness, pouring good; and mixed naphthalene superplasticizer concrete workability described in Test No. slump (mm) Setting time h Compressive Strength (MPa) 0h 1.5h 7d 28 11 195 good workability 8:25 10:20 12 130 25.8 40.9 good workability 10.30 25.4 40.2 8.30 200 150 13 185 125 viscous 8:25 10:25 25 39.3 slightly bleeding phenomenon, test the gas content of approximately 2.8 %, Shandong ready-mixed mortar admixtures, there are more large bubbles. From the concrete appearance quality is better than watching the polycarboxylic acid admixture of naphthalene superplasticizer. Recognized as the world's excellent performance superplasticizer, polycarboxylate superplasticizer exhibited a series of very good performance. Usually mainly in the following aspects: (1) low dosage, high dispersion. Water reduction up to 30%, Henan ready-mixed mortar admixtures, at 0.2% -0.5% of the dosage you can give concrete and mortar of high liquidity; (2) the slump is good, within 90min slump substantially without loss; and (3) at the same liquidity situation, little effect on the cement setting time can be a good solution to reduce water, air entraining, retarding, bleeding and other problems; (4) and cement, blended materials Other types of concrete admixture good compatibility with traditional superplasticizer such as aliphatic superplasticizer compound can produce a good additive effect; high-strength building materials (Figure) | Henan ready-mixed mortar additives | ready-mixed mortar plus agents provided by the high-strength building materials Linyi City Limited.
