The invention discloses phase-change mass concrete and a preparation method thereof. The phase-change mass concrete is prepared from the following materials in parts by weight: 150-200 parts of water, 400-500 parts of cement, 800-900 parts of fine aggregate, 1000-1100 parts of coarse aggregate, 50-100 parts of a modified phase-change composition, 50-100 parts of expanded perlite, 30-50 parts of shell powder and 5-10 parts of a water reducing agent. According to the phase-change mass concrete and the preparation method thereof, the modified phase-change composition, the expanded perlite and the shell powder are added, so that the fireproof and temperature-rise-resistant performance of the concrete can be improved, meanwhile, the problem of internal stress cracking caused by temperature difference can be avoided, and the service life of a building is greatly prolonged.
本发明公开了一种相变大体积混凝土及制作方法，由以下重量份的材料制作而成：水150‑200份、水泥400‑500份、细集料800‑900份、粗集料1000‑1100份、改性相变组合物50‑100份、膨胀珍珠岩50‑100份、贝壳粉30‑50份、减水剂5‑10份。本发明的相变大体积混凝土及制作方法通过加入改性相变组合物、膨胀珍珠岩、贝壳粉，可以增加混凝土的防火、抗温升性能，同时能够避免因为温度差所造成的内应力开裂问题，从而大大增强了建筑寿命。
