3 Things about making the proper concrete

The characteristics and concrete properties are very dependent on the mix design and the quality of the constituent materials, each stage in the concrete production process in the field plays an important role in producing quality concrete.

1. Placement and storage of materials

Sand & Split.

Placement errors and material storage may lead to a decrease in the quality of concrete.
The placement of sand and splint (coral) should be such that not to be mixed by other materials.
The use of a foundation for the stock of materials is strongly recommended in order to prevent the carrying of the soil during pickup.

Cement.

It is maintained that it is not humid, stored in a room or warehouse and underneath it is given a foundation so that the floor vapor is not directly about cement, because when steam is about cement, the quality of the cement decreases and some will harden, turning into coarse grain granules.

2. Preparation and Mixing Process.

To produce concrete with uniform quality, the concrete constituent materials must be prepared and carefully grounded because it will affect the homogeneity of the mixture, mixing can be done manually or mechanically, manual mixing that is using human power with hoe and scoop equipment recommended for volume work Large concrete should be done mechanically.

Mechanical mixing is by means of a mixer, to get a good mixture it takes a minimum of 50 rounds of the mixer or not less than 1 minute for a 1 m3 casting volume.
Concrete stir thickness must be adjusted by means of transportation, a method of compaction, type of construction concerned and density of reinforcement. The viscosity depends on many things. The number and type of cement, the value of the cement water factor, the type and arrangement of grains of the aggregate and other auxiliaries.

To prevent the use of concrete is too dilute or solid, take a minimum slump value of 5 cm and maximum 15 cm.

3. Compaction.

It is carried out shortly after the concrete is poured, with the aim of minimizing the amount of cavity formed in the concrete so that the concrete has high strength. And add water to the water.
