Use of Water Reducers, Retarders, and Superplasticizer
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.
- What are superplasticizer admixtures?
- The superplasticizer admixtures evaluated are of recent commercial development by the cement industry and comprise admixtures based on melamine (Me), vinyl copolymer (VC), and polycarboxylates (PCE1, PCE2, and PCE3). The three polycarboxylates differ in their structural parameters.
- Which admixture exerts the greatest plasticizing properties in all cement formulations?
- Taking into account the results obtained through the different tests to evaluate the fresh state properties, it has been obtained that the admixture PCE3 is the one that exerts the greatest plasticizing properties in all cement formulations, regardless of whether they are hydrated or alkali-activated.
- Are superplasticizer admixtures suitable for OPC?
- Superplasticizer admixtures are designed for OPC so, in presence of supplementary cementitious materials, such as metallurgical slags and combustion ashes, or in alkaline environments, their performance may differ.
- What is the difference between Polycarboxylate ether and superplasticizer admixture?
- As a consequence, the proportion of water necessary in the formulation is reduced . On the other hand, one of the most common superplasticizer admixture families currently used is polycarboxylate ether with branched side chains.
- Does increasing chemical admixture content improve GPC workability?
- Increasing chemical admixture content improves GPC workability up to 115%. Although, it improves workability it results in slight increases in water absorption and porosity, and decrease in compressive and tensile strength and modulus of elasticity.
- What are plasticizing cementitious admixtures?
- 3.1. Chemical stability of admixtures in AAC: FTIR analysis Plasticizing cementitious admixtures are designed to improve the properties of Portland cement, which is hydrated with water that has a neutral pH. On the contrary, in AAC, solutions with higher pH are needed to hydrate/activate the cement.
