Grouting material for assembly type building reinforcement connection sleeve

InactiveCN107686314AGood water retentionIncreased compressive and flexural strength of mortarRebarPliability
The invention discloses a grouting material for an assembly type building reinforcement connection sleeve. The grouting material is prepared from the following raw materials in percentage by weight: 45-60% of cement, 30-45% of fine aggregates, 1-2% of an enhancer, 0.05-0.1% of a de-foaming agent, 7-10% of a phosphogypsum composite expanding agent, 0.5-0.8% of a polycarboxylic acid water reducer, 0.05-0.09% of a retarder, and 0.08-0.2% of an early strength agent, wherein the phosphogypsum composite expanding agent is a mixture of modified phosphogypsum, phosphorus slag micro powder and wollastonite. According to the grouting material disclosed by the invention, continuously graded fine sand and quartz sand are used as fine aggregates to match with the cement for use, the fine aggregates andthe cement are reasonably proportioned, and the phosphogypsum composite expanding agent is added, so that cement paste is very compact after being hardened; the grouting material is greatly improvedin strength, is matched with the enhancer, the retarder, the polycarboxylic acid water reducer and the early strength agent for use, so that mortar has good water-retaining property, plasticity and flexibility; and tensile bonding strength as well as mortar and brickwork tensile bonding strength are obviously improved, comprehensive properties are good, and using requirements of an assembly type building are met.

Preparation method of salt-resistant water-absorbent resin with high water absorption rate

ActiveCN103709309AGood water retentionGood salt toleranceSolventChemical industry
The invention relates to a preparation method of salt-resistant water-absorbent resin with a high water absorption rate. The preparation method comprises the following step: copolymerizing monomers acrylic acid and 2-acrylamide-2-methyl propanesulfonic acid through a free radical polymerization method by taking water as a solvent, taking an ammonium persulfate and tetramethyl ethylenediamine redox system as an initiator, and taking N, N'-methylene bisacrylamide and nanosilicon dioxide as cross-linking agents to obtain the salt-resistant water-absorbent resin with the high water absorption rate. The salt-resistant water-absorbent resin with the high water absorption rate is applied to the fields such as agriculture, forestry, medicines, hygienic materials, buildings, daily-use chemical industry, food and environmental protection. According to the method disclosed by the invention, synthesis reaction conditions are mild, materials are easily available, cost is low, monomer conversation rate is high and product treatment is convenient. The prepared salt-resistant water-absorbent resin in high in water adsorption amount, and has a water-absorption multiple about 2000 times at most within 1 minute in pure water, and the water-absorption multiple of 1800 times at most within 1 minute in normal saline; besides, the resin has good adaptation for different application conditions, and is convenient to popularize and apply.
