Description

This Excel sheet contains all raw data required to reproduce the work reported in the manuscript. The aim of the paper is to investigate the effects of different levels of microsilica (MS) and colloidal nanosilica (CS) on workability, mechanical properties, electrical resistivity, water absorption and ultrasonic pulse velocity of self-compacting lightweight concrete (SCLC). for this purpose, a total number of 16 concrete mixtures with two water to binder (w/b) ratios of 0.35 and 0.45 were considered. The percentages of MS that replaced cement were 0% and 10% and the percentages of CS that replaced cement were 0%, 1%, 3% and 5%. Slump flow (time and diameter), V-funnel flow time, J-ring, and U-box tests were conducted on the fresh concrete and results are shown in 2nd to 6th columns. For all the concrete mixes, compressive strength, split tensile strength and flexural strength (modulus of rupture) were determined at the age of 28 days and results are shown in 7th to 9th columns. Apart from measuring the workability and mechanical properties of SCLCs, the electrical resistivity, ultrasonic pulse velocity and water absorption tests were also performed(see columns 10th to 12th).
