Effect of Sand Combination on Strength of UHPC Based on Toufar Model

Abstract

Abstract: In order to investigate the influence of sand gradation on the strength of ultra-high performance concrete (UHPC), sand was divided into 5 grades by screening test, and the particle size ranges of grade 1 to grade 5 of sands are 1.25 mm to 2.5 mm, 0.63 mm to 0.63 mm, 0.315 mm to 0.63 mm, 0.16 mm to 0.315 mm and 0.08 mm to 0.16 mm, respectively.Based on the test data of sand combination of 3&4 and 3&4&5, the Toufar model was modified and verified, respectively.Then, the modified Toufar model was used to determine the maximum characteristic compactness of 4&5, 2&3&4&5 and 1&2&3&4&5. The four kinds of sand combinations (4&5, 3&4&5, 2&3&4&5, 1&2&3&4&5) were used in the mix proportion design of UHPC, and their strengths were measured. The research results show that the modified Toufar model can be used to calculate the maximum characteristic compactness of sand combination and the mass ratio of different grade of sands in UHPC mix proportion design. When the mass ratio of 3, 4 and 5 grade of sands is 1:0.35:0.473, the compactness of the sand combination is the maximum, and the correponding flexural strength and compressive strength of UHPC are the largest.

Key words: ultra-high performance concrete (UHPC), sand, Toufar model, characteristic compactness, strength, sand combination
