C30 concrete mix ratio using ballast. Particular cement to ballast mix ratio to create C30 grade of concrete should be 1:4 (1 part of cement mix to 4 parts of ballast. Ballast is premix of sharp sand and course gravel or aggregate. This concrete is a common commercial concrete mix typically used for outdoor projects such as pavements.

2024年6月13日 · C30混凝土的配合比为：水175kg，水泥461kg，砂512kg，石子1252kg。 该配合比的比例关系为：水：水泥：砂：石子 = 0.38：1：1.11：2.72。 根据《混凝土结构设计规范》GB50010-2010，混凝土分为C15至C80共十四个强度等级。

强度标准值是立方抗压强度总体分布中的一个值，强度低于该值得百分率不超过5%，即有95%的保证率。混凝土的强度分为c7.5、c10、c15、c20、c25、c30、c35、c40、c45、c50、c55、c60等十二个等级。 注：《gb50010-201…

The mix ratio for C25 concrete is typically 1:2:3, which means 1 part cement, 2 parts fine aggregate (sand), and 3 parts coarse aggregate (gravel or crushed stone). The mix ratio for C30 concrete is typically 1:1.5:3, which means 1 part cement, 1.5 parts fine aggregate (sand), and 3 parts coarse aggregate (gravel or crushed stone).

The mix ratios for C20, C25, C30, C35, and C40 concrete are as follows: C20: 1:2:4; C25: 1:2:3; C30: 1:1.5:3; C35: 1:1:2; C40: 1:1:1.5; The numbers represent the ratio of cement, fine aggregates, and coarse aggregates, respectively. For example, in C30 concrete, there is 1 part cement, 1.5 parts fine aggregates, and 3 parts coarse aggregates.

2024年7月29日 · c30混凝土中水、水泥、砂、石子的配合比是0.38：1：1.11：2.72，因此一方c30混凝土大约需要370kg水泥。 砂为512kg，石子为1252kg。

C30 混凝土配合比是指混凝土中水泥、骨料、水和掺合料的比例关系，它是混凝土设计的关键部分。在建筑施工中，C30混凝土常用于一些对强度要求较高的构筑物，如桥梁、高层建筑、地下室等。下面是一个C30混凝土配合比表的示例： 类别 水泥（kg/m³） 砂（kg/m³）

Understanding the right concrete mix ratios for different concrete grades—like C20, C30, C40 and beyond—can make or break your construction project. Whether you’re an architect, engineer, or DIY enthusiast, knowing how to choose the right concrete grade is crucial for ensuring the strength and durability of your structures.

Here’s are the mix ratio for C12/15, C16/20, C20/25, C25/30 & C30/35 concrete: A typical mix ratio for C12/15 concrete could be 1:2:4 by volume, which means 1 part cement mix to 2 parts sand and 4 parts coarse aggregates mixed with 0.6 parts water. That is, 1 bucket of Portland cement mixed with 2 buckets of sand and 4 buckets of stone.

C30 Concrete Mix Ratio: C30 is a high-strength concrete mix that is suitable for heavy-duty structures such as high-rise buildings, parking structures, and bridge piers. The mix ratio for C30 concrete is 1:1.5:3, meaning one part of cement, one and a half parts of fine aggregates, and three parts of coarse aggregates.
