普通混凝土采用大掺量掺入磨细矿渣和粉煤灰后得到复合胶凝材料混凝土，在此基础上，采用脱硫石膏替代粉煤灰，研究不同脱硫石膏掺量对混凝土胶砂强度和混凝土强度的影响。结果表明，脱硫石膏掺入可改善混凝土早期和后期强度，脱硫石膏掺量占掺合料总量8%，即胶凝材料中SO3含量在2.7%时，复合胶凝材料混凝土早期强度可提高12%，后期强度也可保证。

Composite cementitious material concrete is made by adding large amount of grinded slag and coal ash. This research is conducted using desulphurization gypsum instead of coal ash to find out the effects on the mortar strength and compressive strength caused by different desulphurization gypsum amounts. The tests show that by adding desulphurization gypsum the compressive strength can be improved at both early and later stages. When the desulphurization gypsum takes up to 8%of the total admixture, SO3 within 2.7%, the improvement of compressive strength at early stages increase by 12%and at later stages strength also increase, but not obviously.
