WebWhat causes street creep? Concrete is prone to thermal contraction and expansion. In the summer months, concrete will be slightly larger. In the winter, it will be slightly smaller. Contractors often place small gaps between slabs of concrete, referred to as expansion joints, to prevent slabs from expanding into each other and cracking. WebWhy does concrete creep occur? The creep originates in the calcium silicate hydrates (C-S-H) of hardened Portland cement paste. It is caused by slips due to bond ruptures, with … hisingsrundan
