Special Issue Information

Dear Colleagues,

The shortage of raw construction materials, high carbon emissions in the cement industry and the huge maintenance cost of existing structures are critical obstructions hindering the sustainable development of concrete infrastructures. Due to the innovative efforts undertaken by the research community, satisfactory achievements have been reached in terms of advanced materials, featured structures as well as retrofitting materials and technologies. The application of high-performance, low-carbon and recycled construction materials, together with innovative structure systems, is a trend facing the above-stated challenges. This Special Issue plans to provide a platform for the overview of the state-of-the-art in this research field. Topics of interest include (but are not limited to):

Low-carbon cementitious materials;
Concrete with recycled solid wastes;
Recycled fiber-reinforced concrete;
Innovative FRP strengthening and retrofitting;
FRP bar concrete structures considering ductility demand;
High-performance structure system and theory;
Ultra-high-performance concrete.

Abstract

The paper deals with the effectiveness of various types of polymers (naphthalene formaldehyde, polycarboxylate, and lignosulfonate) as superplasticizers of concrete mixtures based on low-clinker slag Portland cement. Using the mathematical planning experimental method and statistical models of water demand of concrete mixtures with polymer superplasticizers, as well as concrete strength at different ages and under different curing conditions (normal curing and after steaming) were obtained. According to the models, the superplasticizer’s water-reducing effect and relative change in concrete strength were obtained. The proposed criterion for evaluating the effectiveness and compatibility of superplasticizers with cement takes into account the water-reducing effect of the superplasticizer and the corresponding relative change in concrete strength. The results demonstrate that the use of the investigated superplasticizer types and low-clinker slag Portland cement allows for achieving a significant increase in concrete strength. The effective contents of various polymer types, which allow the achieving of concrete strengths from 50 MPa to 80 Mpa, has been found. Full article

Abstract

Using eggshell powder (EP) to replace partial cement in cement-based materials can abate pollution caused by eggshell discard and cement production. In this paper, the surface property of EP and its influence on cement hydration were studied. Quartz powder (QP) and limestone powder (LP) were used as references. First, the chemical composition of EP was characterized. Then, the surface charge properties of these materials were analyzed using zeta potential measurement. The interactions between EP surface and Ca²⁺ were discussed based on the zeta potential test. Afterward, a scanning electron microscope (SEM) was applied to observe the morphology of hydrates on the surfaces of these materials. The results indicated that, although the compositions of EP and LP are similar, the surface charge properties are significantly different. This is likely due to the existence of organic matter on the surface of EP and the difference in the atomic structure. As shown from the zeta potential test, EP exhibits similar interaction with Ca²⁺ as QP. The interactions between EP surface and Ca²⁺ are much weaker than that between LP and Ca²⁺. These weak interactions lead to the growth of C–S–H on the surface of EP particles less than that of LP particles. The chemical reactivity of EP can be improved by using heat treatment, electrical oven, etc. This study will provide theoretical support for the better use of EP in cement-based materials.
