The concrete additives for strength in concrete
The concrete additives for strength is an admixture that can greatly reduce the amount of mixing water under the condition of the same slump of concrete. The plasticizer is a kind of concrete admixture that can reduce water consumption under the condition of keeping the slump of concrete basically unchanged. Mostly anionic surfactants, lignosulfonate, naphthalene sulfonate formaldehyde polymers. After adding the concrete mixture, it has a dispersive effect on cement particles, can improve its workability, reduce water consumption per unit and improve the fluidity of concrete mixture; Or reduce the amount of cement per unit, save cement. The concrete additives for strength in the concrete slump is basically the same, can make mixing water consumption reduce the admixture by more than 15%.

The concrete additives for strength: Types, Advantages & Disadvantages
THE concrete additives for strength
The concrete additives for strength is also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. The concrete additives for strength allows a 30% or more reduction in water content.
It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concretes.
They achieve a reduction in water content without loss of workability.
The concrete additives for strength - Peramin - Imerys Aluminates
The concrete additives for strength enable to achieve high flow properties and reduce water content in self levelling compounds and screed technology
The concrete additives for strength, is high-range water reducing additives used when the dispersion of particles in suspension is required to modify mortars and concrete to allow:
A large reduction of the water content, without affecting their workability:
Improvement of properties: shorter setting time, lower shrinkage and higher mechanical strengths
Or a greater flowability, with the same water content:
Decrease of viscosity, resulting in excellent flow properties
Very good self-levelling properties
Typically, the dosage normally lies in the range of 0.1%-0.8% of the dry mortar total weight, depending of the kind of The concrete additives for strength and performance required.

Kenya recycles plastic waste into bricks that are stronger than concrete
Nzambi Matee of Nairobi, Kenya, is throwing bricks on the pavement of a school made from recycled plastic made in her factory.
It makes a bang, but it doesn\'t crack.
"Our product is almost five to seven times stronger than concrete," says Matee, founder of Gjenge Makers, a Nairobi-based company that converts plastic waste into durable building materials. "They can\'t handle garbage anymore; They can\'t recycle. This is what we get, "Marty said, walking past bags of plastic trash.
Matee gets free waste from the packaging plant, though she pays for the plastic she gets from other recyclers. Matee is a materials engineer who designs her own machines. She said her factory has recovered 20 tons of waste plastic since it was set up in 2017. She plans to add another, larger production line that will triple capacity and hopes to break even by the end of the year.
