Abstract

The present invention relates to semi-precast elevated concrete element system, comprising the following components: (i) a precast concrete panel with partially embedded reinforcing elements for shear transfer and reinforcement for additional load capacity, and (ii) an in-situ cast upper layer of a concrete having an estimated net dilation of at least 75 με at an infinite time; wherein the in-situ cast upper layer of concrete comprises: hydrualic cement being a Portland cement or blended cement: 200 to 700 kg/mof concrete, more preferred 225 to 600 kg/mof concrete and even more preferred 250 to 500 kg/mof concrete; water, at a ratio of watenhydraulic cement of 0.30 to 0.75 by weight, preferably from 0.30 to 0.65 by weight; aggregate, with a maximum size of 40 mm, preferably with maximum size of 30 mm and aggregate:concrete ratio from 0.45 to 0.85 by volume; fiber reinforcement, 10 to 200 kilograms of steel fiber per cubic meter of concrete, more preferred 15 to 150 kilograms of steel fiber per cubic meter of concrete; and/or 0.2 to 30 kilograms of synthetic polymer fiber per cubic meter of concrete; and/or 1 to 100 kilogram of synthetic mineral fiber per cubic meter of concrete; chemical prestressing additive: 1 to 30% by mass of hydraulic cement and sufficient to achieve the positive net length change target above; wherein the chemical prestressing additive is a mineral admixture adapted to create hydration products, which are volumetrically larger than the volume of the reactants when added to plastic concrete; where the length change at an infinite time and drying conditions of 50% relative humidity and 20° C is estimated by plotting the length change data collected in accordance with ASTM C 157 as a function of the inverse square root of time and extrapolating the infinite shrinkage after 28-days of drying.
