Preparation process of foam concrete
The invention discloses a preparation process of foam concrete, which is characterized by comprising the following preparation steps of: a, preparing foam: taking a certain amount of foaming agent, filling the foaming agent into a dilution bottle, and diluting and stirring according to a dilution ratio of 1: 50; starting a small foaming machine to prepare foam, and measuring the prepared foam according to the required volume; b, stirring the materials: adding the cement, the fly ash, the sea sand and the thickening agent into a stirrer, and stirring; c, adding a water reducing agent, namely dissolving the water reducing agent in the mixed water, pouring the mixed solution into a stirrer, and uniformly stirring to form cement mortar; d, adding foams: adding the foams prepared in the step a into a stirrer in batches, and uniformly blending the foams into the cement mortar to form foam concrete mortar; and e, molding in a mold: pouring the foam concrete mortar into the mold for molding after stirring is completed, and obtaining the foam concrete after standard curing. The preparation method has the advantages that the stability of foam in the foam concrete can be improved, and the phenomena of deformation and cracking are avoided; moreover, chloride ions brought by the sea sand are utilized, so that the early strength of the foam concrete is ensured, the strength under the standard curing condition is improved, and the curing cost is reduced.
本发明公开了一种泡沫混凝土的制备工艺，其特征在于：其制备步骤如下：a、制备泡沫：取一定量的发泡剂装入稀释瓶中，按照1:50的稀释比例进行稀释及搅拌；启动小型发泡机制取泡沫，将制备好的泡沫按所需体积量取；b、搅拌物料：将水泥、粉煤灰、海砂及增稠剂加入搅拌机中搅拌；c、加减水剂：先将减水剂溶于拌合的水中，再将混合溶液倒入搅拌机中搅拌均匀并形成水泥砂浆；d、加入泡沫：将步骤a中制备的泡沫分次加入搅拌机中，使其均匀融入水泥砂浆中形成泡沫混凝土砂浆；e、入模成型：搅拌完成后将泡沫混凝土砂浆倒入模具中成型，在标准养护后获得泡沫混凝土。优点是：本发明能提高泡沫混凝土中泡沫的稳定性，避免形变和开裂现象的发生；以及，利用海砂带入的氯离子，保证了泡沫混凝土的早期强度，提升了标准养护条件下强度，减少了养护成本。
