Preparation process of early-strength desulfurization ash-based concrete
The invention discloses a preparation process of early-strength desulfurization ash-based concrete, which comprises the following steps: crushing desulfurization ash, screening, mixing and stirring the screened desulfurization ash, an alkaline admixture and water, and aging after stirring to obtain pretreated desulfurization ash; the pretreated desulfurization ash, the material slag powder, the additive and the alkaline additive are mixed and then ground to obtain a cementing material, the cementing material, the sand, the coarse aggregate and the mixing water are mixed and stirred to obtain the desulfurization ash-based concrete, the desulfurization ash is pretreated, ammonium salt and ammonia water in the desulfurization ash are effectively eliminated, the performance of the cementing material is improved, and the desulfurization ash-based concrete is prepared. The activity and hydration rate of the concrete are improved, the compressive strength of the concrete can be improved, and the comprehensive performance of the concrete is effectively improved.
本发明公开了一种早强型脱硫灰基混凝土的制备工艺，包括以下步骤，对脱硫灰破碎处理并进行筛分，筛分后的脱硫灰与碱性掺合料、水分混合搅拌，搅拌后进行陈化处理，得到预处理脱硫灰，将预处理脱硫灰、料渣粉、外加剂以及碱性添加剂混合后进行研磨得到胶凝材料，将胶凝材料与砂、粗骨料和拌合水进行混合并搅拌得到脱硫灰基混凝土，通过对脱硫灰进行预处理，有效消除脱硫灰中的铵盐以及氨水，提高凝胶材料的性能，提升混凝土的活性以及水化速率，并且可以提升混凝土的抗压强度，有效提升混凝土的综合性能。
