Estimating of long term concrete magnesium sulfate resistance up to 450 days depending on cement impact and water cement ratio
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 1
Abstract
Sulfate attack is a complex form of deterioration that has damaged concrete structures throughout the world. Sulfate attack is particularly complex because the source of sulfates can be external or internal. The sulfate resistance of concretes containing different cement contents, water cement ratios, and C3A percentages is investigated in which concrete specimens were subjected to magnesium sulfate solution up to 450 days. Three cement contents as 350, 400, and 450 kg/m3 were used at different three water cement ratios (0.40, 0.50, 0.60) and three C3A percentages (4.24%, 6.87%, 10.84%). Concrete sulfate resistance was estimated based on measurement of four different mechanical properties; cube compressive strength, tensile strength, modulus of elasticity, and linear expansion strain. These mechanical properties were measured after different sulfate attack periods; 28, 60, 100, 200, and 350 days. Results of this study show that cement content increasing improved concrete sulfate resistance when the concrete is subjected to sulfate attack. Moreover, concrete with high water cement ratios, and C3A percentages showed low sulfate resistance. Concrete with low water cement ratios, and C3A percentages provides an good performance for sulfate resistance.
