The effect of cement type and plasticizer addition on concrete
Three different plasticizer (SP, P and LS) effects on the viscosity of L and N cement paste investigations show that SP addition most efficiently reduces viscosity in pastes of both types of cement, P addition moderately, and LS addition increases viscosity.

Despite the fact that P addition facilitates the plastification of N-type cement, it is also suitable for L-type paste plastification, as after 10–20 min, viscosity growth is stabilised and viscosity values, compared to the addition-free paste viscosity indicators, are mitigated by almost double.

The effect of cement type and plasticizer addition on concrete properties
in cement may affect interaction between the plasticizer and the cement [9]. According to researches [4,10–12], contrary to other types of cement, e.g. pozzolanic cement, with Portland cement all existing types of plasticizer can usually be used. It has been con-rmed that during the process of manufacturing high-performance concrete with a
- How do plasticizers and water reducers affect concrete strength?
- Since the heat of hydration of mass concrete goes down when the cement weight goes down, plasticizers can do this. Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength.
- How do Plasticizers make concrete stronger and last longer?
- Plasticizers make concrete stronger and last longer by reducing the amount of water and cement needed to reach a certain level of workability. Since the heat of hydration of mass concrete goes down when the cement weight goes down, plasticizers can do this. Plasticizers and water reducers are chemical admixtures used to make concrete more workable.
- 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.
- Do admixtures affect the plasticising function of Portland cement?
- However, these admixtures are designed targeted to Ordinary Portland Cement (OPC) and, as a consequence, their plasticising function can be affected by the presence of supplementary cementitious materials or suffer denaturalization for alkaline environments .
- What is a plasticizer in concrete?
- and more resistant to cold. A plasticizer is an additive used in concrete to improve its workability, performance, and durability. Plasticizers are typically added to concrete mixes to make pouring, shaping, and finishing easier. They can also help to increase the strength and reduce the permeability of the hardened concrete.
- 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.
