Towards green concrete: Study the role of waste glass powder
A decline in absolute zeta potential value (close to 0 mV) is noted with the subsequent increase of the replacement percentage of WGP in blended cement. The net charge on the surface of the particles strongly affected the adsorption behaviour of superplasticizer on cement particles and therefore on its compatibility with blended cement.
Towards green concrete: Study the role of waste glass powder
The compatibility of two widely used superplasticizers, polynaphthalene sulfonate-based, and polycarboxylate-based superplasticizer, with blended cement incorporating different percentages of soda-lime waste glass powder, was studied in this paper.
Compatibility of superplasticizers with cement paste and
The compatibility of different families of superplasticizers with various types of cement and mineral admixtures is the prime criterion for selecting a suitable superplasticizer (SP) at an optimum dosage in a concrete mix. The comparative performance of polycarboxylate (PCE) and naphthalene (SNF)-based superplasticizers on the various properties of cement paste and concrete mix containing Type
Superplasticizer compatibility with cement properties – A study
Our paper reports the addition of high performing superplasticizer -Poly Carboxylate Ether in cement composites as per Indian Standards has resulted in a denser cementitious matrix and higher...
Cement and Superplasticizer Combinations: Compatibility and
This study highlights the notion of robustness of combinations of cements and superplasticizers. Tests done with various cements and different families of superplasticizers showed that although a combination of a cement and a superplasticizer could be compatible, it is not necessarily robust.
- Are superplasticizers compatible with SCMS Blended Low carbon cement?
- With expanding cement demand, the need for chemical admixtures has also increased. This comprehensive study focuses on the compatibility of commercially available superplasticizers with SCMs blended low carbon cement and their influence on fresh and hardened properties along with microstructural and durability aspects.
- Can superplasticizer be used with low carbon cement?
- Interaction of superplasticizer with the cementitious mix are presented. Compatibility of commercial superplasticizers with low carbon cement is discussed. Effective use of modified superplasticizer is under-represented in the field of low carbon cements. Ongoing research work on use of superplasticizer and cellulose polymer is presented.
- Does blended cement react with superplasticizer?
- However, our knowledge about how these SCMs cements react with superplasticizers and their impact on fresh, hardened, and microstructural properties is insufficient. In this paper, the interaction of blended cement with superplasticizer was studied. To sum up, the following conclusions can be drawn: 1.
- Does superplasticizer reduce water demand while maintaining workability of blended cement?
- To sum up, the following conclusions can be drawn: 1. It is expected that superplasticizer will lower the water demand while maintaining workability of blended cement. Especially PCE-based superplasticizers are more effective as their absorption by blended cement particles is often higher.
- Is superplasticizer adsorption isotherms of silica fume blended cement?
- Superplasticizer adsorption isotherms of Silica Fume blended cement [ 64 ]. When GGBFS is replaced with cement in mortar without superplasticizer, the yield stress tends to increase and plastic viscosity tends to decrease with replacement rate. Although this opposite behaviour also depends on the particle size distribution of GGBFS.
- Does superplasticizer chemistry affect hydration kinetics of blended cement?
- A higher dose of superplasticizer is required for blended cement, especially LS-MK blended cement. Although workability at saturation dosages of superplasticizer is similar for all binder systems. 3. Superplasticizer chemistry have significant consequences for the hydration kinetics and phase development of blended cement. 4.
