Anti-freezing cracking concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses anti-freezing cracking concrete and a preparation method. The concrete comprises polyoxyethylene sorbitan monostearate, sodium di-sec-octyl maleate sulfonate, coarse aggregate, fine aggregate, cement and water. The preparation method of the concrete comprises the following steps: 1) adding the polyoxyethylene sorbitan monostearate and the sodium di-sec-octyl maleate sulfonate into water, and heating to 75-80 DEG C to obtain a first mixture; and 2) adding the first mixture, the cement and the fine aggregate into the coarse aggregate, and uniformly mixing to obtain the anti-freezing cracking concrete. The anti-freezing cracking concrete provided by the invention can improve the freezing resistance and impermeability of the concrete, and the preparation method provided by the invention can improve the workability of a concrete mixture.
本申请涉及混凝土领域，具体公开了一种抗冻开裂混凝土及制备方法。混凝土包括聚氧乙烯山梨醇酐单硬脂酸酯、顺丁烯二酸二仲辛酯磺酸钠、粗集料、细集料、水泥、水。混凝土的制备方法为：步骤1），取聚氧乙烯山梨醇酐单硬脂酸酯和顺丁烯二酸二仲辛酯磺酸钠加入水中，加热至75‑80℃，获得第一混合物；步骤2），取第一混合物、水泥、细集料加入粗集料中，混合均匀，获得抗冻开裂混凝土。本申请的抗冻开裂混凝土可以提高混凝土的抗冻性和抗渗性。本申请的制备方法可以提高混凝土拌合物的和易性。
