Construction method of gypsum-based indoor floor self-leveling concrete and construction surface structure of gypsum-based indoor floor self-leveling concrete
The invention discloses a construction method of gypsum-based indoor terrace self-leveling concrete and a construction surface structure thereof, and the construction method comprises the following steps: adding phosphogypsum and an additive into a stirrer according to a ratio, uniformly stirring, then adding gravel and water into the stirrer according to a ratio, and continuously uniformly stirring to obtain the gypsum-based indoor terrace self-leveling concrete. And after being determined to be qualified, the concrete is pumped or manually unloaded to a required construction working surface, the compactness required by construction is achieved by virtue of the mobility of the concrete, paving and vibration are not needed, and natural curing is performed for 14 days. The gypsum-based indoor terrace self-leveling concrete prepared by the invention is specially used for indoor terraces, has the effects of early strength, self-leveling, self-compaction, no shrinkage, no need of maintenance, low cost and environmental protection, has the slump of more than 250 mm, the expansion degree of more than 650 mm and the 1d compressive strength of more than 10.0 MPa, has the cost lower than that of cement concrete with the same grade, and can be widely applied to indoor terraces. And the goals of energy conservation, carbon reduction and cost reduction are achieved.
本发明公开了一种石膏基室内地坪自流平混凝土的施工方法及其施工面结构，包括以下步骤：将磷石膏和外加剂按比例投入到搅拌机中搅拌均匀，然后将砂石和水按比例投入到搅拌机中继续搅拌均匀，得到石膏基室内地坪自流平混凝土，测定合格后通过泵送或人工卸载至所需施工作业面，靠自身流动性达到施工要求的密实度，不需要摊铺和振动，自然养护14d即可。采用本发明制成的石膏基室内地坪自流平混凝土专用于室内地坪，具有早强、自流平、自密实、不收缩、无需养护、低成本、绿色环保的效果，塌落度在250mm以上，扩展度在650mm以上，1d抗压强度可达到10.0MPa以上，成本低于同标号水泥混凝土，达到节能减碳、降低成本的目标。
