Durable concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses durable concrete and a preparation method thereof. The durable concrete is prepared from 300 to 500 parts of cement, 600 to 700 parts of fine aggregate, 650 to 780 parts of coarse aggregate, 150 to 200 parts of water, 5 to 7 parts of water reducing agent and 100 to 230 parts of admixture, the fine aggregate is a continuous grading fine aggregate with the particle size of 0.16 to 2.5 mm; the coarse aggregate is a continuous grading coarse aggregate with the particle size of 5-20 mm; the preparation method comprises the following steps: stirring and mixing the coarse aggregate, the fine aggregate, the admixture and the cement to obtain a mixture; and adding the water reducing agent into water, stirring and mixing, adding into the mixture, and stirring and mixing to obtain the durable concrete. The durable concrete provided by the invention has relatively high compactness and high mechanical strength, is not easy to crack after being used for a long time, and has good durability.
本申请涉及凝土技术领域，具体公开了一种耐久性混凝土及其制备方法。一种耐久性混凝土包括300～500份水泥、600～700份细骨料、650～780份粗骨料、150～200份水、5～7份减水剂和100～230份掺合料；细骨料为粒径在0.16～2.5mm的连续级配细骨料；粗骨料为粒径在5～20mm的连续级配粗骨料；其制备方法为：将粗骨料、细骨料、掺合料和水泥搅拌混合后，得到混合料；将减水剂加入水中，搅拌混合后，再加入混合料中，搅拌混合，得到耐久性混凝土。本申请的耐久性混凝土具有较高的密实度，力学强度高，长期使用后，不易开裂，具有良好的耐久性。
