Admixtures and additives for concrete - PCC Group

The best results can be obtained by using polymer concrete admixtures. As a result of their action, the concrete mix is liquefied, the porosity of the concrete decreases, and its durability and strength increases. Superplasticizers are used, among others, in the production of sprayed concrete, self-compacting concrete and concrete elements.

Abstract: The random analysis of the process of chloride diffusion in concrete is a basis of the reliability assessment for durability of concrete structures. In this paper, the diffusion coefficient with time-dependent is introduced to Fick's second law, and perturbation stochastic finite element method (SFEM) with time-dependent(TD) is proposed.

Abstract

The components from which the pervious concrete is made correspond to those of normal concrete with a difference in the grain size gradation where, only one coarse grain fraction or two non-adjacent fractions are used to achieve a porosity of 11 to 35% (1-3).In addition, the fine aggregate is omitted completely or added in a very small percentage, so that it is known as no-fines concrete (4).

Concrete Durability is considered an essential characteristic of concrete structures exposed to the aggressive environment. Evaluating concrete durability using traditional laboratory tests is time–consuming and elaborate. Also, using non–destructive tests (NDT) requires the use of sophisticated and costly tests. Chloride–induced corrosion is the most deterioration mechanism worldwide.
