本品是一种性能优良的新型液体混凝土外加剂，可解决工地施工因使用粉剂速凝剂而出现的粉尘污染问题，顺应了矿山、井巷、隧道等地下工程采用湿法喷射混凝土新技术的潮流，它能使混凝土在喷射后的几分钟内凝结，硬化，提早发挥混凝土同岩体形成整体支承结构的承载，具有喷层厚，回弹量少等优点，操作方便，工效高，劳动强度低，浪费少。本品主要用于铁路或公路隧道、冶金、煤炭、矿山的井巷、硐室以及水电、军工、人防等地下工程的喷射混凝土或喷射砂浆支护。本产品严格按照JC477-92生产，初凝时间在20±30C掺量为水泥用量的3~6%，水灰比0.4的条件下，可使水泥浆在5分钟内初凝，10分钟内终凝。掺本剂的1：1.5水泥砂浆的1天的抗压强度不小于7Mpa，28天强度比（与不掺者相比）不小于75%。、含固量为40%。
Accelerating agent (one kind of concrete apposition agent, effect having prompt solidification) tasting the new model liquid concrete apposition agent being one kind of high performance originally , the dust may resolve a construction site being under construction appearing because of using the powder accelerating agent contaminates a problem, adjustment the mine , underground engineerings such as well alley , tunnel adopt wet process to jet concrete new technique tidal current , it can make a concrete coagulate within several minute of the queen who jets , hardens, shift to an earlier time bringing the concrete and the rock mass into play forming architectural bearing the weight of overall supporting, Have gush the tier is thick , springback amounts stop waiting for merit , operation is convenient , work efficiency is high , labour intensity is low , the dissipation is few. The product is used for railroad or vehicular tunnel mainly , the metallurgy , coal , the mine well alley , c
