Jul 1, 1994When should you add superplasticizers to the mix? How will a change of brands affect set time and slump loss? High-range water reducers are classified by ASTM C 494,

Liquid plasticizers are measured and added to the truck at the plant. So, by the time the truck arrives at the job, the superplasticizer is no longer at its maximum effectiveness. The ability to

We have a wet batch plant, and do not experience many problems when we add it at the plant. The problem comes when contractors add the plasticizer on the job site. It is

Superplasticizers can reduce water demand in the matrix by as much as 30%, and, because they can be added into the transit mixer at the plant and again at the jobsite, workability can

The impact of different components in RC from different sources on the adsorption of superplasticizers should be investigated. This includes assessing the surface charge

The adsorption mechanism of superplasticizers is partially different from the WRA. The difference relates to compatibility between Portland Cement and superplasticizers. It is necessary to

Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. Plasticizers are chemical compounds that enable the

performance superplasticizers in the same ready-mixed concrete plant . However, these classic materials and PCEs are not totally compatible with one another, which leads to the question as to which material needs to be carried on the vehicle in the

When should you use a premium superplasticizer?
You can use a premium superplasticizer when you need a more extreme change in the slump or if you have a project that requires more compressive strength after the concrete has set. Superplasticizers are formulated to reduce the water content of your concrete mix, but during the summer months, this can make your concrete set up even faster.
What is a superplasticizer & how does it work?
Superplasticizers are formulated to reduce the water content of your concrete mix, but during the summer months, this can make your concrete set up even faster. That is why Fritz-Pak developed two superplasticizer products that combine the powerful actions of plasticizers with the qualities of a delayed set admixture.
What is a superplasticizer in concrete?
Superplasticizers allow 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.
When should a superplasticizer be dispensed?
Proper timing is very important, as any delay ranges between one to five minutes after the water addition will result in excessive retardation of setting time. The Superplasticizers should be dispensed on to the batch immediately before discharge for placement (Type F) or with the last portion of the water (Type G).
Does superplasticizer cause air spikes?
In Eastern Washington across eight-plus concrete plants and many aggregate sources we do see air spikes from the addition of superplasticizer. Going from a mix without superplasticizer to an identical mix containing superplasticizer we typically have to reduce the air entraining admixture content by 50% to maintain the same air content.
What are the different types of superplasticizers?
There are four types of superplasticizers: sulfonated melamine, sulfonated naphthalene, modified lignosulfonates and a combination of high dosages of water reducing and accelerating admixtures. Commonly used are melamine based and naphthalene based superplasticizers.
