Performance research based on limestone powder doped with aluminate cement
The invention discloses a performance research based on limestone powder doped with aluminate cement, which comprises the following components by weight: 0-180 g of limestone powder, 270-450 g of CA-50 aluminate cement, 1350 g of fine aggregate and 225 g of water, the particle size of the limestone powder is less than 100 [mu] m, the particle size of the CA-50 aluminate cement is less than 100 [mu] m, the particle size of the fine aggregate is less than 100 [mu] m, and the particle size of the water is less than 100 [mu] m. The concrete mixture is prepared from CA-50 aluminate cement particles and limestone powder, the particle size of the CA-50 aluminate cement particles ranges from 10 micrometers to 80 micrometers, the aggregate is machine-made medium sand with the fineness modulus of 2.5, the particle size of the limestone powder is smaller than that of the aluminate cement particles, and samples in different proportions are mixed to obtain the concrete mixture. Through research on performance changes such as setting time, compressive strength, internal temperature of slurry and hydration products, further optimization of composition and grading of a limestone powder-aluminate composite system is facilitated, so that economic benefits are achieved.
本发明公开了一种基于石灰石粉掺入铝酸盐水泥后引发的性能研究，包括石灰石粉、CA‑50铝酸盐水泥、细骨料和水，各成分及用量如下：石灰石粉为0‑180g、CA‑50铝酸盐水泥为270‑450g、细骨料为1350g、水为225g，所述石灰石粉的粒径均在100μm以下，而CA‑50铝酸盐水泥颗粒粒径在10‑80μm之间，而骨料为细度模数2.5的机制中砂，所述石灰石粉粒径细于铝酸盐水泥颗粒，所述将不同比例的试样混合将得到混凝土混合物，本发明合成的混凝土混合物，通过研究其凝结时间、抗压强度、浆体内部温度、水化产物等性能变化，有利于进一步优化石灰石粉‑铝酸盐复合体系的组成与级配，从而达到经济效益。
