Selling sand and ready concrete lubricant in Karaj

Concrete is one of the practical and very important materials in the construction industry, and additives are usually used for the efficiency and desired result of this building material. Lubricants are chemical additives to concrete. And they are used to increase the amount of concrete slump and reduce water. Types of concrete super-lubricants make concrete more fluid. And they fill the empty spaces of concrete easily.

Every structure that is produced needs to be strengthened and strengthened. One of the materials that gives strength to these structures is concrete. These materials need to be handled and paid at certain times. One of the materials used to polish concrete are lubricants, which have three important degrees of lubrication. Types of concrete super-lubricants or super-lubricants are an example of them, the most important reason for the production of these materials is to reduce the water consumption during the production of concrete, and it increases the strength of concrete. This material penetrates all the pores of the concrete, reduces the air trapped inside the concrete and increases the strength of the concrete. A good concrete usually has good resistance. High modulus of elasticity, good flexibility and low permeability are the characteristics of suitable concretes. These lubricants and types of concrete super-lubricants are added to concrete to strengthen these characteristics so that the concreting process can be done more easily. These lubricants can be added to concrete at the time of construction or concreting.

These super-lubricants are common materials and additives in concrete, which are available in liquid and powder form in the market. The most important types of concrete super-lubricants are in four categories in the market. These categories include the following:

This concrete additive greatly reduces the ratio of water to cement in concrete and makes it more durable by reducing the permeability of concrete against chemicals. By adding this super-lubricant to the concrete mixture or even cement mortar, it causes the pregnancy layer of its molecules to be placed next to the cement particles and separate them. The hydrophobic force of this additive attracts large molecules by cement particles and moves water molecules away from cement particles, which causes the concrete mixture or cement mortar to flow. After some time these charges are destroyed by reverse induction. The concrete slump falls and the setting process begins. These materials are used in ready-made parts. And in narrow sections that have a lot of reinforcement, it is used for dense and prestressed concrete underwater, as well as explosion-proof concreting.

It is a type of concrete super-lubricant that is based on naphthalene and has suitable mechanical characteristics for the construction of concrete structures and is produced and used in cool and moderate climates. This product is produced from synthetic polymer that increases the initial and final strength of concrete without reducing the amount of water and reduces the permeability and durability of concrete. Among the features of this product, it can be mentioned that it increases the properties of pumpability and workability in the workshop, obtains appropriate rheology, and reduces the separation of concretes. The use of naphthalene-based concrete super-lubricants in making concrete that absorbs a small percentage of water, making high-strength concrete, quick pumping of concrete and concreting, concreting of beams, bridges, shear walls, concrete containing sand grains and They don't have good sand.

This chemical substance is one of the types of concrete super-lubricants, which reduces the amount of water consumed and increases the fluidity of concrete, and is effective in concrete slump and adhesion. Reducing and increasing the time it takes plays an important role in the final concrete. This super lubricant is effective in cement and water consumption. Accurate calculation of the quality and type of final concrete reduces the cost and time of vibration operation and increases the fluidity of concrete and increases compressive strength. It reduces concrete cracking and makes reinforcement and concrete stick.

This is one of the types of concrete super-lubricant that lowers the water tensile level of concrete, increases the cement particles, spreads it better and helps in better lubrication of concrete. This additive prepares the paste. which is smooth and easier to work with and makes the structures highly resistant. As the molar mass of ligno-based superlubricants increases, its lubricating power increases. Of course, it is difficult to dissolve the powder samples of this material and it leaves a little sediment in the final mixture. This product can be used in concreting with a pump, reducing the amount of water drop, concreting shear walls, beams, columns, and causing material adhesion in case of improper grading.

Types of super-lubricating concrete can be effectively used to prepare various requirements in projects. Concrete manufacturers can better use these lubricant additives to increase slump without adding water. Contractors can also use a variety of super lubricants for ease and speed of placement and compaction processes. Because simplifying the processes causes less manpower to be used and even construction activities are carried out faster.

In the first step and before calculating the amount of lubricant in concrete, a product should be selected according to the conditions, location, time of concrete pouring, sectioning, stone materials used, the distance of carrying concrete to the desired location, initial and final slump, concrete mixing plan, Choose the initial and final strength of concrete. The amount of lubricant used (water reducer) or the amount of super-lubricant used in concrete is different in the production of slabs or concrete. Factors such as the base of water reducing materials, mixing percentage, compounds in concrete, project implementation conditions, type or material of stone materials, temperature, final slump and water mixing percentage play an important role in determining the amount of lubricant. The percentage of mixing is usually obtained based on experiments and workshop samples. Accordingly, in all concrete additives from a ratio between 0. 2 to 2 percent of cement volume is used. That is, based on the type of project and the mentioned cases, it can be about 0. 2 to 2% of the weight of cement was assigned to water reducing materials or lubricants.

The question of most consumers is that if there is no accurate information about the amount of lubricant in concrete, what is the solution? In such cases, the only way to determine the effect of additives on concrete is to perform laboratory tests. In these tests, factors such as weather, equipment, concrete preparation method and other consumables are usually considered. All the parameters that are likely to be changed in the combined mortar design will be calculated in this test. Measurements and calculations should be checked several times in the workshop. This method will prevent mistakes in determining the amount of lubricant. After that, the sizes for the most suitable mixing plan can be considered as the main criterion for the consumption of water reducing materials. Based on the information included in valid domestic and international regulations and standards, precise solutions have been defined for calculating the amount of lubricant.
