Slag-waste marble powder based alkali-activated high-strength concrete and preparation method thereof
The invention discloses slag-waste marble powder-based alkali-activated high-strength concrete and a preparation method thereof, and belongs to the technical field of green building materials. The invention provides slag-waste marble powder based alkali-activated high-strength concrete. The slag-waste marble powder based alkali-activated high-strength concrete is prepared from the following raw materials in parts by weight: 338-489 parts of mineral powder, 122-250 parts of waste marble powder, 121-318 parts of water glass, 24-59 parts of sodium hydroxide, 4-14 parts of a composite additive, 28-142 parts of water and 1080 parts of fine aggregate. The prepared slag-waste marble powder based alkali-activated high-strength concrete has good physical and mechanical properties and has the characteristics of early strength and high strength, the 3-day compressive strength of the concrete can reach 70 MPa or above, the construction period can be shortened to a certain extent in actual engineering, the construction efficiency can be improved to a certain extent, the 28-day compressive strength of the concrete can reach 90 MPa or above, and the service life of the concrete is prolonged. And the requirements of most high-rise buildings and large-span projects on compressive strength can be met.
本发明公开了一种矿渣‑废大理石粉基碱激发高强混凝土及其制备方法，属于绿色建筑材料技术领域。本发明提供的一种矿渣‑废大理石粉基碱激发高强混凝土，包括以下重量份原料：矿粉338～489份、废大理石粉122～250份、水玻璃121～318份、氢氧化钠24～59份、复合外加剂4～14份、水28～142份、细骨料1080份。本发明制备的矿渣‑废大理石粉基碱激发高强混凝土具有良好的物理力学性能，兼具早强和高强的特点，其3天抗压强度能达到70MPa以上，在实际工程中能在一定程度上缩短施工周期，提高施工效率，其28天抗压强度能达到90MPa以上，能满足大部分高层建筑和大跨度工程对于抗压强度的需求。
