Anonymous users2024-02-06C30 concrete is calculated based on the strength of the benchmark concrete.
Standard strength = 30+
Cement selection of cement empirical strength of 48MPa
Water-glue ratio = (48*.)
If the collapse degree is 90mm, the amount of cement is 215kg with water
If the average amount of c30 is 2400kg per side, the amount of sand and gravel = 2400-370-215 = 1815kg
Stone selection is small, 10-20mm, gravel sand rate is selected 40%, then the amount of sand = 1815 * 40% = 726kg
Gravel dosage = 1815 * (1-40%) = 1089kg
Cement: 370 Sand: 726 Gravel: 1089 Water 215
This is just the benchmark matching, for example, with a high-efficiency superplasticizer, the compressive strength ratio is 130% higher than the benchmark, the early strength is higher, the water is used less, and the amount of cement is reduced.
If you use a water reducer, the amount of cement is 280kg, and each square can meet the strength requirements, you can choose to add fly ash admixture to reduce the amount of cement, which is more economical, I hope it can help you.

Anonymous users2024-02-04Summary. Generally, the amount of C40 concrete per cubic cement is about 500-550 kg, 800 kg of sand, and about 1200 kg of stone; It is best to use medium sand for sand.
How much cement, sand, gravel do you need for one cubic of concrete, how much cement, sand, gravel, water reducer do you need for one cubic concrete.
Generally, the amount of C40 concrete per cubic cement is about 500-550 kg, 800 kg of sand, and about 1200 kg of stone; It is best to use medium sand for sand.
Don't you use a water reducer?
Wait a minute, I'll take a look.
The general parameter is the amount of cement 8 12, for example, your C40 concrete, you can check the mix ratio to know that the approximate cement dosage in 1 square concrete is 400 kg, then if the admixture parameter is 8, then the admixture dosage is 32 kg. Good.

Anonymous users2024-02-03The water-cement ratio is, the sand rate is, water consumption per cubic meter = 190kg, cement consumption = 422kg, gravel consumption = 1252kg, sand consumption = 536kgThis slump is 35mm.
The principle of determining the reasonable sand rate is: the amount of sand fills the void of the stone with a slight surplus. The sand rate has a great impact on the workability, strength and durability of concrete, and also directly affects the amount of cement, so the optimal sand rate should be selected as much as possible, and adjusted according to the fineness modulus of the sand, the requirements of the slump, etc., and the conditional matters are determined by the test.

Anonymous users2024-02-02Cement:About tons (160 kg).
Sand:About tons (piper 320 kg).
Stones:About tons (560 kg).
Therefore, a cubic C30 cement + sand + gravel mass defeat ratio of concrete requires about tons of cement, tons of sand and tons of stones.

Anonymous users2024-02-01Calculate the weight of water, cement, sand and gravel required to mix 2 cubic meters of C30 concrete.
The weight of water, cement, sand and gravel required for mixing and excavating old 2 cubic meters of C30 concrete is as follows: 1Water:
According to the water-cement ratio, the water consumption per cubic meter of C30 concrete is 180kg. Therefore, the weight of water required for 2 cubic meters of C30 concrete is 2m 180kg m = cement:The standard mix ratio of C30 concrete is:
Cement: sand book loose cover: stone =:
3。Therefore, the amount of cement used in 2 cubic meters of C30 concrete is: 2m 1 (1 + 1000kg m = sand:
According to the mix ratio: 3 calculation, the weight of sand required for 2 cubic meters of C30 concrete is 2m 1450kg m = stones: according to the mix ratio:
3 calculated, the weight of the stone required for 2 cubic meters of C30 concrete is 2m 3 (1 + 1600kg m = 1440kg. Therefore, the weights of water, cement, sand and gravel required to mix 2 cubic meters of C30 concrete are 360kg, 260kg, 435kg and 1440kg respectively.

Anonymous users2024-01-30C20 concrete mix ratio water:,cement:1,sand:,stone:,How to calculate the material per cubic meter?
Dear, I am glad to answer for you: the C20 concrete mix ratio with a particle size of 20 is water: cement:
Sand: gravel =: 1::
C20 concrete mix ratio is: 1::. 2. That is, 190kg of water is needed per cubic meter, 404kg of cement, 542kg of sand, and 1264kg of stone.
Concrete is divided into several strength grades according to its strength, and the strength grade of concrete is divided according to the standard value of cubic compressive strength fcu,k. The standard value of cubic compressive strength is a value in the overall distribution of cubic compressive strength, and the percentage of strength below this value does not exceed 5%, that is, there is a guarantee rate of 95%. The strength of concrete is divided into twelve grades.
C20 can be used for general non-trunk roads, Conglupeng Township roads, etc., ordinary 3-storey residential buildings, ground and other pouring can be, if it is 5 floors or more now mostly seepage then C25, beam C30 concrete.
