specific Embodiment 1
[0038] A waterproof and anti-cracking mortar composition is composed of quartz sand, cement, light calcium, hydroxypropyl methylcellulose, anti-cracking fiber, starch ether and redispersible rubber powder. Among them, the specification of quartz sand collection is 60 mesh; the viscosity of hydroxypropyl methylcellulose is more than 250,000; the specification of anti-cracking fiber collection is 6 mm.
[0039] The components and ratio of the composition are as follows: 60% of quartz sand, 25% of cement and 15% of light calcium are combined to form a ton of raw materials, and then 8 kg of hydroxypropyl methylcellulose is added to the above-mentioned one ton of raw materials element, 15 kg of anti-crack fiber, 1 kg of starch ether, and 3 kg of redispersible rubber powder.
[0040] The preparation method of finished mortar composition is as follows:
[0041] 1. Combination of aniseed materials: first put the quartz sand, cement and light calcium into the mixer according to the am...
