Abstract:
In this paper, it was successfully established a novel and cheap water-proofing
technique for protecting concrete from further damage caused by water leakage. This
technique originated from the proper design and rational formulation of the materials
including hydrophobic sand, silicon oil, tyre crumb rubber, and recycled motor oil.
From this research, it can be seen that only one concrete showed hydrophobicity and
all obtained concrete demonstrated significantly and in some cases extremely low
water permeability relative to control concrete. To the best of current knowledge, this
is the first paper, which studied the surface and water sorption properties of concrete
modified by the addition of hydrophobic sand obtained by patented technology. The
goniometer investigated the surface properties of the modified concrete. The results
obtained including density, contact angle, change of weight, and maximum load
capacity under high electro-hydraulic pressure were compared and discussed.
