Optimal regime in slip form concreting
The rise rate of the form is the principal parameter of casting quality in slip form concreting. Experimental data are presented, which show that the optimal rate is the maximum one, subject to the
Short-term steam-curing and concrete later-age strength
The effect of steam curing on later-age strength of concrete was studied on mixes having the nominal cement content of 150 to 400 kg/m3. Three series of tests were involved in which the delay period
Effect of curing and composition on the properties of the outer skin of concrete
The effects of curing in mild, hot, and dry conditions on strength and quality of concrete skin were studied. The skin quality was determined by absorption tests and depth of carbonation (natural and
The evaluation of the crack-bridging ability of exposed roof coatings
A major problem with single-layerin situ applied or prefabricated roofing membranes, exposed to intensive solar radiation in subtropical climates, is their long-time ability to bridge over working
Effect of Water-Cement Ratio and Curing on Chloride Penetration into Concrete Exposed to Mediterranean Sea Climate
The effect of water-cement ratio (w/c) and curing regime on chloride ion ingress of 20 x 20 x 12 cm concrete specimens exposed to Mediterranean Sea climate was studied. Variants included w/c of 0.4,
Development of a Scratch-Test Instrument for Thick Wall Coverings
While establishing performance specifications for building elements, the authors have recognized the fact that there is no available test method for the direct investigation of scratch resistance of
A simple pull-out test for in situ determination of early strength of concrete
The aim of the work reported was to develop a simple non-destructive testing method for monitoring strength development between 5 MPa and 15 MPa for form stripping in industrialized building.
