Evaluation of the Efficiency of Different Waterproofing Products in Concrete for Sustainability

The efficacy of several waterproofing products in concrete, such as integrated waterproofing compound, water-repellent cement and waterproofing coatings with acrylic and styrene-butadiene latex co-polymer bases was assessed in this experimental study. The mechanical properties, durability and fresh concrete parameters were examined and a comparison was related to control concrete-concrete that had not been treated with any waterproofing compound. Concrete with an integrated waterproofing chemical exhibited the largest slump of 56 mm, whereas the concrete with water-repellent cement displayed the highest density of 2459 kg/m3. Concrete with integral waterproofing chemical showed the best compressive strength of 39.33 N/mm2, flexural strength of 5.85 N/mm2 and split-tensile strength of 3.80 N/mm2, respectively, at 28 days. Cube specimens treated with an acrylic base water-proofing coating showed a minimum average rate of water absorption of 0.36 and a minimum sorptivity of 0.022 mm/min0.5, after 48 hours. It was concluded that the best result for mechanical properties was shown by concrete with an integral waterproofing compound, whereas the concrete with acrylic-based waterproofing coating was the best performer in terms of durability parameters.
