The invention discloses high-strength anti-cracking masonry mortar and a preparation method thereof, and relates to the technical field of building materials. The masonry mortar comprises the following raw materials: medium sand, fine sand, cement, heavy calcium carbonate, fly ash, aluminum dihydrogen phosphate, a binder, a water reducing agent and an anti-cracking agent. The preparation method of the masonry mortar comprises the following steps: adding medium sand, fine sand, cement, ground calcium carbonate and fly ash into a stirring box, then adding a binder, and stirring and mixing to obtain an intermediate material; adding aluminum dihydrogen phosphate, and uniformly mixing to obtain a mixture; and adding a water reducing agent and an anti-cracking agent, and uniformly mixing to obtain the high-strength anti-cracking masonry mortar. The mortar has the advantages that the medium sand and the fine sand are mixed with the cement and the fly ash according to a specific proportion, the rheological property of the mortar is improved by adding the heavy calcium carbonate and the aluminum dihydrogen phosphate, the bonding strength of the mortar is better by combined use of the binder, the water reducing agent and the anti-cracking agent, stirring and mixing are more sufficient during preparation, and the mortar has a good anti-cracking effect. And the prepared mortar has higher overall strength and cracking resistance.
本发明公开了一种高强度抗裂砌筑砂浆及其制备方法，它涉及建筑材料技术领域。砌筑砂浆包括以下原料：中砂、细砂、水泥、重质碳酸钙、粉煤灰、磷酸二氢铝、粘结剂、减水剂、抗开裂剂。砌筑砂浆制备包括以下步骤：将中砂、细砂、水泥、重质碳酸钙、粉煤灰加入搅拌箱内，再加入粘结剂，搅拌混合制得中间料；加入磷酸二氢铝，混合均匀制得混合料；加入减水剂、抗开裂剂，混合均匀得到高强度抗裂砌筑砂浆。本发明的优点在于：采用特定比例的中砂、细砂与水泥、粉煤灰混合，通过加入重质碳酸钙、磷酸二氢铝，改善砂浆流变性能，通过粘结剂、减水剂、抗开裂剂组合使用，砂浆粘结强度更好，制备时搅拌混合更充分，制备的砂浆整体强度和抗开裂性能更高。
