What is the mixture ratio of c25 concrete? What is the compressive strength of c25 concrete?

Concrete mix design is very important in concrete engineering, which directly affects the smooth construction of concrete, the quality of concrete engineering and the cost of concrete engineering. Let's take a look at the mix proportion of c25 Bian Xiao concrete. By the way, the cost and compressive strength of c25 concrete. Interested friends come and have a look.

A, c25 concrete mixture ratio

(a) c25 concrete mixture ratio 1

A, cement: water: sand: gravel = 372:175: 593:1260 =1:0.47:1.59: 3.39;

B, the dosage of trial mixing materials is: cement: water: sand: crushed stone = 8.5: 4.0:13.52: 28.82kg;

C, after mixing, slump is 30mm, meet the design requirements.

(2) c25 concrete mix ratio 2

A cement: water: sand: gravel = 417:175: 579:1229 =1:0.42:1.39: 2.95;

B, the dosage of trial mixing materials is: cement: water: sand: crushed stone = 9.6: 4.03:13.34: 28.42kg;

C, after mixing slump is only 20mm, can not meet the design requirements. Therefore, keep the water-cement ratio unchanged, increase the dosage of cement by 500g, and increase the mixing water by 210 g. After mixing again, the slump reaches 35mm, which meets the design requirements.

E, at this time, the actual dosage of each material is: cement: water: sand: crushed stone =10.1:4.24:13.34: 28.42kg. ..

Second, how much is c25 concrete?

How much is the concrete surface of 1 and c25? According to the market price, it is generally between 200 and 500 yuan. Prices are different in different regions; Sent to different places, the price is different; Different doses and time lead to different prices. There are differences in prices in different places, mainly due to the different prices of ground materials (sand and gravel), different transportation distances, different strength grades, and different volumes of concrete.

2. Concrete refers to the floorboard of engineering composite materials in which aggregates are bonded into a whole through cementing materials. Generally speaking, the term concrete refers to cement as cementing material and sandstone as aggregate; Cement concrete, also known as ordinary concrete, is made by mixing and stirring water (including admixture and admixture) in a certain proportion, which is widely used in civil engineering.

3. Concrete is divided into C 10, C 15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80, C85, C90, C95 and C65438+.

3. What is the compressive strength of c25 concrete?

1, what is the compressive strength of c25 concrete? The standard value of compressive strength of c25 concrete is 25MPa≤fcu, and the compressive strength of K 30mpa concrete is obtained through experiments. According to GB/T5008 1-2002, a cube with a side length of 150mm was made and cured to 28d under standard curing conditions (temperature 20 2℃, relative humidity above 95%), and the ultimate compressive strength was measured by standard test method.

2. Generally, the standard value of concrete splitting tensile strength is slightly greater than that of concrete, and the axial tensile strength of C25 concrete is 1.78.

3, concrete crack resistance refers to the ability of concrete to resist cracking. The crack resistance of concrete is a comprehensive property, which is related to tensile strength, ultimate tensile deformation capacity, tensile elastic modulus, autogenous volume deformation, creep and thermal properties.

The above is about the mixture ratio of c25 concrete, how much c25 concrete is, and how much compressive strength c25 concrete is. I hope I can help you!
