Super-early-strength ardealite self-leveling mortar
The invention discloses super-early-strength ardealite self-leveling mortar which comprises water and powder, the powder is composed of the following raw materials in parts by weight: 1280-1300 parts of phosphorus building gypsum, 0-13 parts of silicon powder, 2.25-7.0 parts of a water reducing agent, 2.5-3.5 parts of a retarder, 0.4-0.52 part of a defoaming agent, 0.30-0.45 part of cellulose ether, 0.3-0.4 part of a thixotropic agent and 0-30 parts of ash calcium, the mass content of the high-doping-amount phosphorus building gypsum is greater than 96%, a large amount of ardealite can be consumed, and the high-early-strength ardealite self-leveling mortar has the advantages that the high-early-strength ardealite self-leveling mortar can be prepared; the consumption treatment of the ardealite is improved, the resource comprehensive utilization of wastes is facilitated, and the carbon emission is reduced. The 1d compressive strength of the obtained ardealite self-leveling mortar is larger than or equal to 20 MPa, the water content in the mortar is low, the early strength is high, continuous construction can be achieved, the overall construction time of a project is saved, and the construction cost is reduced. Meanwhile, due to the low water-binder ratio, the interior of the mortar is compact, and the softening coefficient is larger than or equal to 0.6 on the premise that a waterproof agent is not doped.
本发明公开了一种超早强磷石膏自流平砂浆，包括水和粉料，粉料由以下重量份的原料组成：磷建筑石膏1280～1300份、硅粉0～13份、减水剂2.25～7.0份、缓凝剂2.5～3.5份、消泡剂0.4～0.52份、纤维素醚0.30～0.45份、触变剂0.3～0.4份、灰钙0～30份，通过高掺量磷建筑石膏，其质量含量大于96％，能够大量消纳磷石膏，提高磷石膏的消纳处置，有利于废弃物资源化综合利用，降低碳排放。获得的磷石膏自流平砂浆，1d抗压强度大于等于20MPa，其砂浆中含水率低、早期强度高，能做到连续施工，节约项目的整体施工时间，降低建造成本。同时通过低水胶比，砂浆内部致密，在不内掺防水剂的前提下，软化系数大于等于0.6。
