C60 pumping concrete and preparation method thereof
The invention discloses C60 pumping concrete and a preparation method thereof. According to the technical scheme, the C60 pumping concrete is characterized by being prepared from the following components in parts by weight: 400 to 420 parts of cement, 130 to 150 parts of an admixture, 690 to 710 parts of a fine aggregate, 960 to 980 parts of a coarse aggregate, 8 to 10 parts of an admixture and 160 to 170 parts of water, wherein the fine aggregate is formed by mixing river sand and machine-made sand in a weight ratio of 3:7, the fineness modulus of the river sand is 0.9-1.1, and the fineness modulus of the machine-made sand is 2.8-2.9; the coarse aggregate is formed by mixing large pebbles and small pebbles in a weight ratio of 6.5:3.5, the particle size of the large pebbles is 10-20 mm, the mud content of the large pebbles is smaller than 0.5%, the particle size of the small pebbles is 5-10 mm, and the mud content of the small pebbles is smaller than 0.6%. The pumping concrete has theadvantages of being high in compressive strength, good in workability and high in pumping height.
本发明公开了一种C60泵送混凝土及其制备方法，其技术方案要点是一种C60泵送混凝土，以重量份数计，包括如下组分：水泥400‑420份、掺合料130‑150份、细骨料690‑710份、粗骨料960‑980份、外加剂8‑10份以及水160‑170份；所述细骨料由重量比为3:7的河砂和机制砂混合而成；所述河砂的细度模数为0.9‑1.1，所述机制砂的细度模数为2.8‑2.9；所述粗骨料由重量比为6.5:3.5的大卵石与小卵石混合而成；大卵石的粒径为10‑20mm，含泥量<0.5%；小卵石的粒径为5‑10mm，含泥量<0.6%。本发明中的泵送混凝土具有抗压强度高、和易性好以及泵送高度高的优点。
