Superplasticizer compatibility with cement properties – A
The cement–admixture (superplasticizer) incompatibility may affect both the fresh state and hardened properties of the cementitious mix - the main ones are rapid loss of workability, excessive quickening/retarding of setting times, low strength gain, excessive air entrainment, and increased risk of shrinkage with moderate cracking.
Poly(carboxylate ether)-based superplasticizer achieves
Flow behavior of cement pastes depends on the physical and chemical interactions among its components: cement particles, admixtures (e.g., superplasticizers and stabilizing agents), and water 12.

from the result gotten from the fresh and hardened properties of effect of superplasticizer at 0.25, 0.30 and 0.35% with 10% fly ash as a mineral admixture in replacement of cement, that increase of the superplasticizer dose lead to marginal reduction in unit weight but addition with gaining self-compatibility of the mixes.
Effect of prehydration of Portland cement on the
This paper presents a case study on the optimization of admixture for use with prehydrated cement by assessing changes in the rheological properties of Portland cement artificially pre-hydrated.
- Does superplasticizer admixture affect concrete quality?
- The experiments were classified into two phases: the first phase focused on the effects of superplasticizer admixture on workability and compressive strength, and the second phase determined the influence of superplasticizer admixture on concrete quality by reducing the amount of mixing water.
- What is a superplasticizer in concrete?
- A superplasticizer is an admixture properties of a concrete mixture. The use of a and hardened states. In the fresh state, use of a content of concrete. I f the water–cement r atio water is available to lubricate the mix. In the compaction to produce dense concrete. In with the presence of a superplasticizer . Liboment–163 is added.
- Does asuperplasticizing admixture affect concrete properties?
- This study aimed to study the effects of asuperplasticizing admixture, namely, Sikament-NN superplasticizer, on concrete properties, such as workability and compressive strength. Experiments were performed on different concrete mixes with water–cement ratios of 0.50, 0.55, and 0.60.
- Is superplasticizer a good choice for hardened concrete?
- The experiment program included tests on workability, slump test, and flow table. For hardened concrete’s compressive strength test, we compared the properties of superplasticizer-based concrete with those of concrete without superplasticizer. The superplasticizer led to a significant water reduction but maintained workability.
- What is superplasticizing concrete admixture used for?
- Our products are good for ready mix concrete used for swimming pools, sea walls, tunnels, bridges, basement, etc. Our superplasticizing concrete admixture products are used in hot climates like Nigeria to produce Precast and ready mix concrete, slabs, basements, foundations, walls, columns and piers.
- Is superplasticizer based concrete good for compressive strength test?
- For hardened concrete’s compressive strength test, we compared the properties of superplasticizer-based concrete with those of concrete without superplasticizer. The superplasticizer led to a significant water reduction but maintained workability. Content may be subject to copyright.
