当前,混凝土中的掺合料种类繁多,混凝土中大量使用以各种工业渣体为主的各种掺和料,在促进混凝土向高性能化的同时解决了渣体的回收利用,减少了水泥的用量,使混凝土与环境更加协调。
本实验是在以碱激发为实验平台。以复掺粉煤灰和锂渣,硅灰等渣体,代替部分矿渣,减少碱矿渣混凝土中的矿渣比例,并对碱矿渣进行改性。研究二元及多元复合渣体在碱激发混凝土中的性能。
锂渣在碱激发混凝土中的作用是起增强和一定程度的增塑作用的。粉煤灰没有增强效果,但增塑和消除碱激发渣体混凝土表面的泛霜效果明显。
碱激发矿渣制备的碱矿渣混凝土是利用化学方法充分激发矿渣的活性,以其作为混凝土的胶结材替代水泥,用其制备的水泥性能非常优越,耐久性好,使用周期长。
由于矿渣已经充分的利用,其他工业渣体其他工业渣体制备复合渣体的碱激发混凝土也必然将产生良好的经济效益。

At present, the 掺 in the concrete matches to anticipate the category numerous, in the concrete various 掺 that regards various industry 渣 body as the lord of a great deal of usage and anticipate, solved the recovery of the body of 渣 to make use of at the time of promoting concrete turned toward high performance, reduce the dosage of the cement, make concrete and environments moderated more.
This experiment is at with the alkali stir up for experiment the terrace.With reply the 掺 powder ash from stove and the lithium 渣s, the 硅 ash etc. the 渣 body, replace parts of mineral 渣s, reduce the mineral 渣 comparison within the alkali mineral 渣 concrete, and carry on changing sex to the alkali mineral 渣 .Study two dollars and the diverse compound 渣 body to stir up the function in the concrete in the alkali.
The lithium 渣 stirs up in the alkali the function in the concrete is to rise to strengthen and certain the degree increases the function of 塑 .The powder ash from stove did not strengthen the result, but increase the 塑 and remove the alkali to stir up the be suffused with of the 渣 body concrete surface frost result obvious.
The alkali stirs up the alkali mineral the 渣 concrete that the mineral 渣 system have is an activity that makes use of the chemistry method to stir up the mineral 渣 well, be the gum knot material of the concrete to act for the cement with it, the cement function that make to have is very superior with it, durable good, the usage period is long.
Because of already full exploitation of the mineral 渣 , other industries of other industries 渣 body 渣 system has the alkali of the compound 渣 body to stir up the concrete also will produce by all means good of economic performance.

At present, the concrete mixing materials range extensive use of concrete in a variety of sports-oriented industrial scrap various races expected, the high-performance concrete in the promotion of sports at the same time addressing the scrap recycling, and reduce the consumption of cement, concrete and the environment in a more coordinated. The experiment was inspired to experiment with the alkali platform. To the taste Fenmeihui and lithium scrap, scrap silicon, grey body instead of slag, slag cement, slag reduce alkali ratio, and a modified alkaline tailings. Binary and multiple research groups in the composite scrap alkali stimulate concrete performance. Lithium residue in the concrete base to stimulate and strengthen the role of a degree of increased supervision role. Fenmeihui not increase effectiveness, but increased supervision and the elimination of alkali stimulate scrap concrete surface pan-cream sports results obvious. Alkali stimulate slag prepared alkali slag concrete is the use of chemical methods fully stimulate the reactive tailings, with alternative materials as cement concrete cement, the cement produced by its excellent performance, good durability, long life cycle. The tailings have been fully utilized, and other industrial scrap body other industrial scrap system for the composite scrap body inevitably would have a concrete base to stimulate good economic returns.
