Concrete water-retaining agent based on high-adsorbability stone powder
The invention discloses a concrete water-retaining agent based on high-adsorbability stone powder. The concrete water-retaining agent is characterized by comprising the following components in parts by weight: 60-70 parts of high-adsorbability stone powder, 20-30 parts of silica fume and 10-20 parts of cellulose ether, the water demand ratio of the high-adsorbability stone powder is not less than 120%; the concrete water-retaining agent which is low in price, convenient to prepare and environment-friendly is prepared by modifying the high-adsorbability stone powder by utilizing the water absorption retention effect of the high-adsorbability stone powder, the concrete production cost can be effectively reduced, and the added value of the high-adsorbability stone powder is improved.
本发明公开了一种基于高吸附性石粉的混凝土保水剂，其特征在于：包括：高吸附性石粉60～70重量份，硅灰20～30重量份，纤维素醚10～20重量份；高吸附性石粉的需水量比不小于120％；本发明利用高吸附石粉的吸水保持作用，将其进行改性后制备成一种价格低廉、制备便捷、环境友好的混凝土保水剂，可有效降低混凝土生产成本，提高高吸附性石粉的附加价值。
