Abstract：Because the strength of full lightweight concrete ( FLC) is affected by many factors, and the ranges of design parameters of mix ratios are also wide in related specifications, which results in difficulties of mix design. Therefore, in order to determine the parameters of the optimal proportions, a series of strength factors on full lightweight shale ceramsite concrete ( FLSCC) are researched experimentally. The test results show that the FLSCC strength depends mainly on the strength of cement mortar and aggregate, and pre-wetted time. The concrete strength and water / binder ( W / B) ratio have also an inverse relationship, but the strength has an upper limit; similarly, sand ratio too. Secondly, the axial compressive strength is similar to the cube strength, and the compressive strength of 7 days is also close to that of 28 days. Thirdly, the stress- strain curve shape of the FLSCC is similar to ordinary one, but the elastic modulus is lower, the peak strains and the total strains are larger. Thusly, it is suitable for anti-seismic and anti-blast and anti-impact structures.
