Self-leveling, self-compacting and high-strength gypsum-based indoor floor self-leveling concrete as well as preparation method and application thereof
The invention discloses a self-leveling, self-compacting and high-strength gypsum-based indoor terrace self-leveling concrete. The self-leveling, self-compacting and high-strength gypsum-based indoor terrace self-leveling concrete is prepared by mixing the following components in parts by weight: 250-700 parts of phosphogypsum, 5-25 parts of an additive, 1400-1950 parts of gravel and water, the ardealite is one of mixed-phase gypsum, alpha-type high-strength gypsum and phosphorus building gypsum. The prepared self-leveling concrete is high in flowability, can achieve an automatic leveling effect when being used for indoor terrace construction, does not need to be vibrated, has the cost lower than that of cement concrete with the same grade, does not shrink and slightly expands, and can achieve the purposes of saving energy, reducing carbon and reducing cost after being used. The mortar has the effects of early strength, self-leveling, self-compaction, no shrinkage, micro-expansion, no maintenance, low cost and environmental protection.
本发明公开了一种自流平、自密实、高强石膏基室内地坪自流平混凝土，所述自流平、自密实、高强石膏基室内地坪自流平混凝土由磷石膏、外加剂、砂石、水按照以下重量份配比混合：磷石膏250～700份、外加剂5～25份、砂石1400～1950份；所述磷石膏为混合相石膏、α型高强石膏、磷建筑石膏中的一种。本发明制得的自流平混凝土流动性强，用于室内地坪施工时能够达到自动找平作用，无需振捣，成本低于同标号水泥混凝土，不收缩微膨胀，使用这种产品后，可达到节能减碳、降低成本的目标，具有早强、自流平、自密实、不收缩微膨胀、无需养护、低成本、绿色环保的效果。
