the gypsum varieties

<p>Cement clinker added to adjust the gypsum varieties, adjust the coagulation gypsum on the admixture of the influencing factors in order of anhydrite (industrial anhydrous gypsum)> semi-hydrated gypsum>  pvc composite decking northern ireland  dihydrate gypsum, and cement manufacturers to save costs are often used hard Gypsum, gypsum-doped cement water demand, the amount of adsorption plus large, additive loss of action on the big. Fourth, the cement fineness and particle size distribution, cement manufacturers to improve cement strength by increasing the fineness of cement, but too fine cement, water demand, the same will absorb a large number of admixtures so that the role of additive loss.</p> <p> The effects of anhydrite on wood calcium and more significant, even there will be acute coagulation (false coagulation) phenomenon. Cement particle grading is not good, large cement paste bleeding rate of cement and additives to adapt less well. Cement alkali content, alkali content is too high or too low cement and some additives react, it will cause  creative way to cover up outside concrete floor  changes in the cement gypsum solubility, so that the cement mineral component C3A speed up the water, water demand increases, loss of work loss Also faster.</p> <p> At this time adding soluble Na2SO4, can improve its adaptability with additives. In actual production, concrete slump loss over time, the problem mainly occurs in the high temperature period, usually by taking the aggregate water cooling approach to reduce the slump loss. Or adjust the additive formula can be mitigated or overcome, such as compounding a small amount of slump ingredients. However, the problem that the admixture has poor initial plasticizing effect on cement can not be solved by simply adjusting the formula of admixture. Concrete manufacturers should analyze the reason based on the experiment, based on the experiment, select the appropriate raw materials  16 by 20 Deck for Sale in Malaysia  through experiments, Refractories Raw material manufacturers to put forward specific quality indicators, requiring stable quality, research and allocation of the right mixture to improve the initial plasticizing effect of concrete.</p>
