Fresh and Hardened State of Polymer Modified Concrete and Mortars – A Review

Abstract

Abstract. Polymer modified concrete or mortar is an alternative to the advancement of long serving civil engineering material -mortar and concrete. The excellence and promising benefits of modified composites have led to numerous progressive studies of its application. This paper presented a critical review from previous research on the polymer modified concrete and mortar. Both fresh and hardened state behaviours were reviewed as they are important for the development of excellent engineering material. Most of the applications of polymer modified concrete and mortar can be seen in diverse types of polymer such as latex, epoxy and emulsion. The utilization of each type of polymers resulted in different characteristics of composite concrete or mortar. Such applications have contributed to the improvement in terms of workability and mechanical strength, especially at higher grade of composite strength of concrete material.

Binders alternative to Portland cement and waste management for sustainable construction – Part 2

“…The combination of conventional concrete and polymeric resins is able to overcome traditional drawbacks of cementitious materials like durability-related issues, weak adhesion to substrates, and low tensile strength. 213,214 Several authors investigated the possibility of recycling PET by a glycolysis process to produce an unsaturated polyester resin to be used as a binder in concrete or mortar preparation. 215–217 Some interesting and promising results were obtained, such as a sharp decrease in water absorption with increasing PET content, but also an increase in compressive strength with increasing resin content.…”

Feasibility Study of SBR-Modified Cementitious Mixtures for Use as 3D Additive Construction Materials

“…In addition, the surfactant included in the polymer itself, the latex, acts like a plasticizer to increase the slump value and reduce the amount of water required. In addition, the strength, adhesion, and water resistance are improved considerably [16,17,18,19]. Due to the advantages of adding SBR latex, the fresh properties of the cementitious mixtures studied here all improved, making them appropriate for 3DAC applications.…”

Strength Development Characteristics of SBR-Modified Cementitious Mixtures for 3-Demensional Concrete Printing

“…When polymer particles are dispersed in a mixture, they behave like ball bearings, facilitating the relative motion of cement particles against hydration particles [15]. Surfactants contained in the polymer latex act in a similar manner, improving the physical and chemical performances of cement mixtures [16][17][18]. This type of water-soluble polymer contributes to cultivating the performance of cementitious mixtures, improving their cost-effectiveness and extending the scope of their application as construction materials.…”
