Self-compacting concrete admixtures Direct

Tel: 13716267347 self-compacting concrete admixtures, Tianjin, Liaoning, Yunnan and Guangxi, Zhejiang and Shanghai and Guangdong Anhui Beijing Chongqing 湖南 湖北 Xinjiang, Hebei, Henan and Ningxia Qinghai, Gansu and Shaanxi, Tibet Guizhou, Sichuan and Hainan Heilongjiang, Inner Mongolia and Shandong, Fujian 吉林 Shanxi, Jiangxi and Jiangsu self-compacting concrete admixture is a non-shrink high-strength, vibration-free concrete admixtures. Concrete can be dense gravity forming, and the hardening process no shrinkage, and good old concrete bond interface. Application of the current international advanced technology, is the company after a years of research and application development of new high-performance concrete admixtures. Particularly suitable for reinforcement especially dense, complex shape, inconvenience vibrated concrete works (especially reinforced concrete works). 1, high mobility; ensure concrete forming dense energy gravity. 2, viscosity cohesion; ensure concrete park during the flow and segregation phenomenon does not occur. 3, high water retention; concrete surface hardening process to ensure no bleeding. 4, high strength; maximum strength up 60-80Mpa. 5, the hardening process does not shrink with high performance micro-expansion and the old concrete bonding strength. Key Features: Work of gravity, forming dense bleeding rate (%) 0 Less water rate (%) 20 26 Compressive strength (MPa) 3 天 20-50 40-100 28 days limit expansion ratio (%) 7 days in water ≥ 0.25 28 days 28 days in the air ≤ 0.10 ≥ 0.010 Usage: 1, self-compacting concrete admixtures no shrinkage in powder form for incorporation, dosage is 6-8% of cement (within the mixed). Packing: 1 bag of 40-50kg, plastic-lined woven bag. Storage: 1, this product should be stored in dry and clean warehouse, pay attention to water, damp, open dumps, but shall not be exposed to rain or damaged packaging. From the date of production, effective storage period is one year, extended or caking before use subject to passing the test. 2, the product is non-flammable, non-drug, capable of general vehicles carrying, transit shall not damage the packaging, moisture or rain. Caution 1, self-compacting concrete admixture is a non-shrink, high-strength, vibration-free concrete admixtures. Concrete can be dense gravity forming, and the hardening process no shrinkage, and good old concrete bond interface. 2, concrete can be used 42.5 (or 32.5) ordinary portland cement, the product Recommended dosage is 6-8 cement (within the mixed), in strict accordance with the construction, measurement of each material ratio should be guaranteed accurate. 3, concrete mixing, added directly in the form of powder. But note that in the cement surface spreading evenly and avoid wet sand, stone direct contact with the concrete mixing time should be extended, do not be vibrating or slightly vibrated into the mold after compaction, concrete should pay attention to strengthening the early conservation, in order to ensure gravity compacting and strength, coarse and fine aggregate gradation must be qualified, but storage should pay attention to moisture. If damp after agglomeration, or crushed before use should be screened after passing the test. 4, the product is intended for use ratio is determined to do first with the content, the other outstanding issues can refer to the relevant job specification.
