Water loss is added to concrete, mortar, or mortar mixture to increase the flow capacity without increasing the amount of water. This is a superplasticizer. Plasticizers can help achieve high, great performance in difficult situations without using too much water. In addition, reducing the water/cement ratio increases the durability of concrete.

The basic products that make up a plasticizer are as under:

Unisonic surfactants such as lignosulphonates and their modifications and derivatives, hydrocarbon sulfonate salts. Nonionic surfactants, such as polyvinyl esters, Hydroxylated carboxylic acids, and their modifications and derivatives. Other products, such as carbohydrates, etc.

Advanced Plasticizer is a newer and relatively improved version of the plasticizer class. Super plastics are used to create flow, self-leveling, and self-compression, and to create high-strength, high-performance concrete contracts.

Can produce high plasticizer:

Concrete especially from 3D Resources can be used more than usual with the same weight/weight ratio, It is allowed to use a lower W / C ratio for equal functions. Due to the increase in strength with a decrease in the water/carbon ratio, it also makes it possible to reduce the cement content.

They are melan formaldehyde sulfonamide (SMF) capacitors, naphthalene formaldehyde sulfonate (SNF) thickeners, and modified lignosulphonates (MLS), based on acrylic polymer (AP), acrylic carboxylic acid co-polymer with the acrylic ester (CAE), cross-linked acrylic polymer (CLAP), polycarboxylic ester (PC), polycarboxylic ether (MCE)

Technically speaking, Superplasticizer is a premium water-reducing and retardant additive. Mechanism: The mechanism of Superplasticizer is known as C3A adsorption (tricalcium aluminates), which breaks the agglomeration by repelling the same charges and releases the trapped water. The adsorption mechanism is partially different from the water reducing adjuvant. The difference concerns the compatibility between Portland cement and Superplasticizer. It is necessary to ensure that the Superplasticizer does not bind to the tricalcium aluminates in the cement particles, which would lead to less workability of the concrete.

A slightly higher amount of Superplasticizer is used to increase the workability of the concrete, ranging from 1 to 3 liters per cubic meter of concrete where the liquid Superplasticizer contained approximately 40% active material. To reduce the water-cement ratio a higher dose is used, that is, from 5 to 20 liters per cubic meter of concrete.

Now, what are the benefits?

Ø  Increases workability so, can reduce the water/cement ratio.

Ø  It can increase compressive strength up to 22,000 psi.
