We experimentally investigated the optimum dosage of casein superplasticizer (SP) in self-leveling underlayments (SLUs). The undersaturated adsorption state of casein in cement pore solution was characterized by zeta potential measurements. Different amounts of casein were dosed in SLU pastes and their dispersion performance was investigated by a mini slump test. Flow values of the SLU pastes were found to increase with casein dosage, but an obvious segregation of the pastes was observed at high dose levels of SP. At an SP dosage of 0.12 wt.% bwob (by weight of binder), a homogeneous SLU paste with a spread flow of >15 cm over a time span of 30 min was obtained, which was identified as the optimum casein dosage for SLUs. Casein was found to adsorb significantly onto the surface of cement, thus producing strong dispersive power at low dose levels.

“…The greater difficulty in the use of fine RCW is related to its high absorption of water [6]. In order to ensure selfleveling behaviour, a greater amount of fine is required to achieve an effective fluidity [7]. Therefore, the use of the fine portion of this residue can be a sustainable solution to manufacture coarse recycled aggregate from recycling plants.…”

The self-leveling mortar is a fluid product that has as a low viscosity and high fluidity. This building material that requires no vibration and leveling, having very low thickness (30 mm). The purpose of this study is to evaluate fresh properties of self-leveling SLU using three byproducts: bottom-ashes, fine elements of quarry limestone and fine elements from recycledconcrete-waste. Portland Cement OPC was partially replaced by 0,10, 15 e 20% of fines. The water/binder was maintained constant at 0.50 and mix proportion 1:2 cement and sand (by weight) was used. Fresh properties were examined: plastic shrinkage, curling and heat measurements using a semi-adiabatic calorimeter. A superplasticizer (polycarboxylate) was used to assure a fluidity. During drying (HR=50%) a mass loss was monitored. To the same cement content fine from bottom-ash acted efficiently to reduce a shrinkage. The curling phenomenon is high, with more than 1.70 for mortars based on fine from recycled-concretewaste. Higher early curling was obtained for mortars with quarry limestone. A good performance could be assured with ternary mixes with bottom ashes (curling less than 8mm). Self-leveling mortar systems with more than 20% of fine resulted negative effect on segregation and bleeding, so not recommended to self-leveling mortar purposes.
