The effect of superabsorbent polymers on the cracking behavior due to autogenous shrinkage of cement-based materials
Abstract
As far as durability is concerned most of the deteriorating mechanisms acting on concrete structures are related to the ingress of aggressive agents inside the structures. Reinforcement corrosion, carbonation and problems during freeze-thaw cycles are related to the ingress of substances such as chlorides, sulfates, carbon dioxide and even water, amongst others. Even before reaching its hardened state, a cement-based composite is subjected to the formation of cracks especially due to the effects of shrinkage during the early ages. The formed porosity of the material can become the perfect path for the ingress of those aggressive agents. The shrinkage phenomena, especially when referred to autogenous and plastic shrinkage are inherent to the hydration process of the cementitious material and (among other factors) are a function of the water-to-cement ratio and curing conditions (temperature and humidity). The use of superabsorbent polymers has proven to be an interesting alternative in the mitigation of shrinkage and reducing shrinkage cracking by means of internal curing. They can also promote sealing and autogenous healing. In this study, different cement pastes and mortars were produced with different combinations of superabsorbent polymers. Their effects on the shrinkage cracking behavior was studied. Both polymers used have already been (individually) studied in previous research and results showed different benefits regarding the crack mitigation and self-sealing and -healing of the samples. In this paper different combinations of those polymers were studied aiming to achieve a composition with optimal properties for the mitigation of autogenous shrinkage. The experimental program of the study was based on the monitoring of autogenous strain and the effect of the polymers in the properties of specimens in the fresh and hardened state. To accomplish that, the hydration and setting time of the mixtures were evaluated by means of ultrasonic measurements (p-wave); the autogenous strain was measured from the final setting time till the age of 7 days following the method described in the ASTM C-1698-09 and mechanical strength tests were also performed.
