Use of superabsorbent polymers to mitigate autogenous shrinkage in ultra-high performance concrete [PDF]
, 2019 Ultra-high performance concrete (UHPC) with low w/c-ratio is very prone to the formation of cracks due to autogenous shrinkage. These cracks can lead to a decreased durability of the concrete, resulting in higher maintenance and/or repair costs in the ...
