In the specific selection process, the following types are respectively selected: the water reducing agent is polycarboxylic acid, the defoaming agent is organic silicon, and the cement modifier is cellulose.
Example two
The embodiment provides a waterproof concrete material which comprises the following components in parts by weight:
5-10 parts of a waterproof agent, 380-400 parts of cement, 190-195 parts of water, 600-700 parts of sand and 1100-1200 parts of stones.
When the waterproof concrete material is specifically manufactured, the following processes are adopted:
8 parts of a waterproof agent, 399 parts of cement, 1191 parts of water, 660 parts of sand and 1140 parts are taken as raw materials respectively, and then the waterproof agent is prepared according to the following steps:
firstly, water and a waterproof agent are mixed to replace stirring water to stir cement, sand and stones, so as to form the concrete material with the volume weight of 2390 and the slump of 80.
EXAMPLE III
The embodiment provides waterproof mortar, which specifically comprises the following components in parts by weight: 4-6 parts of a waterproof agent, 510 parts of cement, 1600 parts of sand and 200 parts of water.
