Crack Mitigation in Concrete: Superabsorbent Polymers as Key to Success?
Cracking is a major concern in building applications. Cracks may arise from shrinkage, freeze/thawing and/or structural stresses, amongst others. Several solutions can be found but superabsorbent polymers (SAPs) seem to be interesting to counteract these problems. At an early age, the absorbed water by the SAPs may be used to mitigate autogenous and plastic shrinkage. The formed macro pores may...
متن کاملPhysical Properties of Concrete Modified with Superabsorbent Polymers
This dissertation deals with the effect of a new concrete additive, called salt-insensitive superabsorbent polymer, on the physical properties of normal and high strength concrete. Superabsorbent polymers, short SAP, are special polymers that are able to absorb many times more water than their own weight within short time. They can even store water when exposed to gentle mechanical stress. When...
متن کاملSuperabsorbent Polymers and Superabsorbent Polymer Composites
This article briefly describes the general aspects and cross-linking polymerization of superabsorbent polymers (SAPs) and superabsorbent polymer composites (SAPCs). Research and development of SAPs has become very active after the Northern Region Laboratory of the United States Department of Agriculture invented the first SAP, used as a soil conditioner. Based on the advancements in organic/ino...
متن کاملFreeze Thaw Durability of Internally Cured Concrete Made Using Superabsorbent Polymers
The use of superabsorbent polymers (SAPs) to produce internally cured concrete has been shown to be effective in reducing the potential for restrained shrinkage cracking of high performance concrete mixtures. However, not much is known regarding the freeze–thaw durability of concrete mixtures that incorporate SAPs for internal curing (IC). When SAP particles desorb (or partially desorb) the “wa...
متن کاملThe Effects of Superabsorbent Polymers on Soils and Plants
Current climate change is projected to have significant effects on temperature and precipitation profiles, increasing the incidence and severity of drought. Drought is the single largest abiotic stress factor leading to reduced crop yields. Given the large share of water use in the agriculture sector and very low efficiency in this sector, selection and development of the new strategies to impr...
