What is the ratio of the various materials in the C25 concrete to the size of the material? The director did not do the building management, say what to estimate the number of sand, stone, cement, I want to get out of this ratio to count, I quickly fainted. I know that one side of the concrete to use about 2.5T cement, but the proportion of gravel and do not know, I can only tell the boss how many kilograms, how many tons forget. Please know how to teach me, it is best to tell me how to count. Question added: I would like to know how much the volume is, the weight is better than I have. 325 # Ordinary Portland Cement more
You are not all right, with the ratio and water-cement ratio is not sure, is not calculated, if in accordance with the general experience in terms of the above two are right. I suggest you download a concrete mix of software, mortar is also together.
Construction with the ratio: Cement: 301 kg (425 # ordinary Portland cement) Sand: 655 kg (in sand) Stone: 1305 kg (5 ~ 40mm gravel) Water 粻 Shan Gang catch the non-stone stem will: 149 Kg The use of the environment for the dry office room slump requirements of 35 ~ 50mm
About 1625 kg; sand: 566kg; stone: 1261kg with the ratio of: 0.44: . the amount of cement, : 1.42: 3.17 you say no, 1 side of the concrete which used 2.5t cement, should be the total weight of about 1 square concrete is about 2.4t or so, the proportion is above I said, according to each party for 2400KG concrete preparation.
