Effects of plasticizer and antifreeze on concrete at
In this study, four concrete mixtures were produced. The mixtures were coded as ref for the concrete without an admixture, P for the concrete with plasticizer, A for the concrete with antifreeze and PA for the concrete with plasticizer+antifreeze. In concrete mixtures, W/C are different in order to keep the slump values equal. Table 1.

Optimizing Polycarboxylate Based Superplasticizer
The use of polycarboxylate ether (PCE) as superplasticizer (SP) in the manufacture of high strength concrete is increasingly common. Each brand of SP available on the market has different...
Influence of superplasticizer on strength of concrete
Abstract and Figures This paper outlines an experimental study that measures the effects of superplasticizer admixture on proprieties of concrete. However, Superplasticizers are the most...
- What is the difference between Orthodox plasticizer and superplasticizer?
- For entire monitoring period there was a difference of approx. 2.0 GPa between the concretes with orthodox plasticizer (P_1 a 2) and concretes with superplasticizers (SP_3 a 4). Upon the set compressive strengths the monitored concretes were classified to particular strength class of concrete.
- What class of concrete is a superplasticizer?
- Upon the set compressive strengths the monitored concretes were classified to particular strength class of concrete. In particular, the concretes P_1 and 2 (plasticizer) met C 30/37 and concretes SP_3 a 4 (superplasticizer) were filed in the strength class C 35/45.
- What are the different types of plasticizers?
- Plasticizers were selected from same producer (Chryso). Different types of plasticizers differing in effects on fresh concrete characteristics were selected. ChrysoPlast 460 is plasticizer based on lignosulfonate and on the other hand ChrysoFluid Optima 224 is a modern type of polycarboxylate based superplasticize.
- What are plasticizers & superplasticizers?
- Plasticizers and Superplasticizers Most of producers of plasticizers (PL) and superplasticizers (SP) adapted to particular user requirements to influence properties of fresh and hardened concretes.
- Do superplasticizers increase compressive strength?
- In the compressive strength setting phase the values were in average by 8.5 MPa higher with concretes containing superplasticizer. The same trend was found also with values of modulus of elasticity development when they got moduli by approx. 2.0 GPa higher at all monitoring periods.
- Can superplasticizer increase modulus of elasticity?
- that ground it is reasonable to apply highly efficient superplasticizer which together with increase of compressive strength may also increase the modulus of elasticity to certain extent. Lower amount of mixing water may reduce the risk of decrease of modulus of elasticity.
