"The first domestic and technologically advanced multi-effect multi-functional admixture". It integrates water reduction, enhancement and coagulation promotion. Among the nine indicators, three have filled domestic gaps and three have caught up with the world’s advanced level. National key new product, 2001 national high-tech new material demonstration project. Since the product was launched in 1997, it has been used in major coal mines across the country, in the spray concrete of Beijing and Shenzhen subways, in the Wanjiazhai Q2 and Q3 loess layers of the Ministry of Water Resources, and in the consolidated grouting of Beijing subway flowing sand layers. The use of soil-nailed walls in deep foundation pits in Dalian Hi-tech City to block water leaks reflects their great vitality.
When XPM admixture is mixed into sprayed concrete, the rebound rate is 6%-8%, the strength is 200%, the thickness of one spraying layer is 350mm~700mm, and the dust concentration is reduced by 50%; during grouting, XPM grouting material, water-cement ratio 0.5, flow rate 14.4S (water 15.5S); mixed with coagulant (powder), the coagulation time can be adjusted from 30S to 60min with the amount of coagulant. The 28-day strength is 170% of pure cement slurry can be poured into a pore opening of 0.1mm, and the cement amount can be saved by 50% in the same section. In the pumped concrete, 425# ordinary silicon cement is used, with a water reduction rate of 28% to 33%, which improves fluidity and enhances anti-seepage durability.
Using XPM anti-leakage agent and XPM plugging plug, it can block leakage against water and control large holes, dog holes, pitted surfaces, seams, and 3MPa pressure water cracks; various Plumbing flooding. XPM admixture is an environmentally friendly material with a bonding force of 3.8MPa, impermeability S40, PH value of 7, and total alkali content of 2.908%; The 12-hour flexural strength is 7MPa, the compressive strength is 53MPa, the 28-day flexural strength is 10.76MPa, the compressive strength is 81.3MPa, and the bonding force is 3.89MPa. It is the first choice material for emergency repairs of airport runways, road pavements, stockyards, and emergency repairs.
XPM admixture, spray concrete admixture, high-strength waterproof pumping agent, anti-seepage plugging agent, high-strength rapid replenishing agent, and nuclear curing admixture series products will provide important solutions for my country's water conservancy dams, highways, and railways. Play its due contribution in key projects such as subways, deep foundation pits, loess layer grouting, mine tunnels, nuclear submarine bases, ports and terminals, and airport runways
