1. What materials does a concrete block need?

To create a concrete block, many different materials are needed. But the most important thing to have is  cement. This is the most important adhesive ingredient that helps materials bond into a durable block. So how much cement does a block of concrete need? Normally, the proportion of cement accounts for about 5 - 7% of the total value of the project.

In addition, a concrete block requires a number of materials such as:

- Sand. In particular, the types of sand that can be used in construction are black sand and yellow sand.

–  Stone is a material that increases the strength of concrete. Types of stone commonly used in construction include 1×2 stone or 4×6 stone.

–  Finally, clean water helps the cement bond the materials into a durable block.

Above are the important ingredients in a concrete block. To get the best finished concrete, it is necessary to inspect and control input materials to ensure quality and limit impurities. In addition, to obtain a standard concrete block for use in construction, it is necessary to mix these materials in an appropriate ratio.

2. Ratio of sand, stone, cement poured into concrete

To have a concrete block that meets standards and is widely used in construction, it is impossible to arbitrarily mix the materials freely. This makes the product less durable and sturdy. At the same time, the concrete surface quickly cracks. Therefore, it is necessary to ensure that the proportion of cement, sand, and stone poured into concrete follows extremely strict and accurate regulations.

To get the best quality for a concrete block, you should mix sand and stone as follows:

The standard sand-cement stone ratio usually makes 1 bag of cement + 4 sand + 6 stones. However, currently, depending on the specific purpose of use for the project, there are different concrete mixing formulas with different cement, sand and stone ratios.

3. Ratio of sand, stone, cement in a fresh concrete block

The ratio of sand, stone, and cement in 1m³ of concrete is essentially the ratio of concrete mix that will depend on the grade of concrete. Specifically, the ratio of sand, stone, and cement in 1m3 of aggregate concrete with standard concrete grades is 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, etc. 

There are a number of tables specifying how to calculate reference rates according to different standards as follows:

3.1 Ratio of sand, stone, cement, water in 1m³ of concrete (Mark 150)

The simple calculation formula is as follows: For example, to get a block (1m3) of grade 150 concrete, you will need 288.025 kg (cement) + 0.505 m³ (sand) + 0.913 m³ (1 x 2cm stone) + 185 liters ( water). However, it should be noted that this is not a fixed formula, because the water ratio in concrete is not determined specifically.

3.2. Ratio of sand, stone, cement, water in 1m³ of concrete (Mark 200)

According to the table above, it can be seen that a block of 200 grade concrete will require 350,550 cement (kg) + 0.481 yellow sand (m³) + 0.9 amount of 1x2cm stone (m³) + 185 liters of water. Do not calculate the specific water ratio in concrete.

3.2 Ratio of sand, stone, cement, water in 1m³ of concrete (Mark 250)

The ratio of 1 block of 250 grade concrete needs to be measured with the formula 415.125 cement ratio (kg) + 0.455 yellow sand (m³) + 0.887 1x2cm stone (m³) + 185 liters of water. Do not calculate the specific water ratio in concrete.

4. Some notes during the concrete mixing process

The process of mixing concrete to produce a quality final product is not necessarily easy. The following are a few notes that will help you be more successful when conducting work:

- Choose a suitable concrete mixer

If you want quality concrete mortar, you cannot ignore the concrete mixer factor. If the equipment is reputable, your product will be more guaranteed. There are many types of mixers depending on different project levels:

• Forced mixer / stationary concrete mixer for small, permanent projects). 
• This type of self-propelled concrete mixer will be suitable for some medium-sized projects. It is required that the machine can be moved from the mixing station to the construction site. 
• Finally, truck-mounted mixing tank equipment is always chosen for large projects.

- Understand how to mix standard concrete

Want to "own" concrete mortar with perfect strength. Exact compliance with the prescribed formula is indispensable. In particular, concrete grade plays a role in expressing the compression resistance of concrete. And there are ratios of 100,150, 200, 250, 300, 400, 500, 600. You want to mix the ratio accurately. Please follow the information written on each bag of cement.

5. Note when starting to mix concrete

Great attention should be paid to the proportion of water added to the concrete. To ensure the most effective mixing quality:

• Adjust the amount of water in the mixture just enough. If there is little water, the mortar will dry quickly. It is difficult to proceed and the concrete does not reach perfect strength. If you pour too much water, the paste will become mushy and will take a long time to develop the concrete mark. Costs a lot to build.
• Because it is impossible to measure the amount of water according to a certain formula. So people ask for help by using machines like centrifuges. Adding spices or mixing with a machine, etc. helps add a minimum amount of water and is easy to apply.
• It is necessary to ensure that the concrete kneading process is carried out continuously. No interruptions affecting concrete quality. To do this, workers need to pay attention to the input quality of cement. Does it have much impact on the hardening process or the adhesion ability of concrete?
