Smart superabsorbent polymers for self-sealing and -healing of mortar
ID No: 54 Abstract: Concrete is an important building material, due to its ease to use and relatively low cost. However, the presence of cracks endangers the durability of concrete and can result in reinforcement corrosion since a pathway for harmful particles dissolved in fluids and gases is generated. Manual repair costs can go up to half of the annual construction budget. Instead, introducin...
متن کاملCrack 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 کاملModeling of Self-Healing Concrete: A Review
Self-healing concrete (SHC) has received a tremendous attention due to its advanced ability of automatic crack detection and crack repairing compared to the standard concrete. Two main approaches which considered as to-date self-healing mechanisms are autogenous and autonomous healing. In the past several years, the effort of the research has been focused on experimental works instead of numeri...
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 کاملBehaviour of Bacterial Concrete as Self Healing Material
The major problem the construction industry concurs with is the high maintenance cost of the concrete. Various natural processes such as weathering, faults, land subsidence, earthquake, changes in moisture and temperature, have the tendency to create cracks in concrete. Therefore, to counter these effects, it has become necessary to come up with ways which will not only help in counteracting bu...
