水化物
    Higher is the temperature,more severely is the structure of concrete destroyed,with more new hydrate crystals generated in the water-cooling concrete.
    受热温度越高,新的水化物晶体就越多,同时混凝土的显微结构破坏越严重。
    Higher H_2S in natural gas with very high sour content has less affect on hydrate formation temperature,which is more evident as pressure drops.
    对特高含硫天然气而言,硫化氢含量越高,对水化物形成温度影响越大,且随压力的降低,硫化氢含量越高对水化物形成温度影响得越大。
    The anti-sloughing mechanisms of modified polyalcohol appear as: ⑴ water absorbing mechanism, that is, the strong water absorbing of modified polyalcohol inhibits the forming of hydrate, so the water absorbing trend of clay in mud shale is reduced;
    改性多元醇的防塌作用机理表现为:(1)吸水机理,多元醇的强吸水性抑制水化物的形成,降低了泥页岩中粘土的吸水趋势;
    Hydration mechanism of coal gangue grouting agent was analyzed in this paper,the results shown that the agent is composed of CSH gel,CH crystal,calcium aluminate hydrate and calcium aluminate sulfate hydrate. Meanwhile the grout also contained unhydrated activated mineral crystal,thus it can ensure the calculus strength had a tendency which continues to increase.
    对煤矸石灌浆材料的水化机理进行了分析,发现浆材的水化物主要为CSH凝胶、CH晶体、水化铝酸钙以及水化硫铝酸钙(AFt)等,同时还有未水化的活性矿物晶相,可以保证结石体强度有继续增大的趋势。
