一种掺入水泥中，形成高抗渗防水层的新型防水材料——抗渗微晶，由同济大学、上海微晶防水材料公司共同研制成功，并已通过上海市建委科学技术委员会组织的产品验收鉴定。抗渗微晶是一种无机刚性材料，它主要利用微晶的原理，掺入水泥中，在水泥水化过程中能形成高强微晶体，? A new type of waterproof material, impervious microcrystalline, which is incorporated into cement to form a high impermeability waterproof layer, was successfully developed by Tongji University and Shanghai Microcrystalline Waterproof Material Co., Ltd., and has passed the products organized by Shanghai Construction Committee Science and Technology Committee. Acceptance test. Impervious microcrystalline is an inorganic rigid material. It mainly uses the principle of microcrystals and is incorporated into cement to form high-strength microcrystals during cement hydration.
