The anionic compound has an air-entraining effect and improves the homogeneity of the concrete mixture.STRIDH, KJELLJOHANSSON, INGEMARSVEDMAN, KJELLNAESLUND, MARITA
A law on the cumulative damage is presented basing on total strain energy induced as damage parameter to calculate the cumulative damage when the specimens of concrete subjected to fatigue loading.Then the maximum of critical cumulative damage and location of production are determined basing on the ...
Steel fibre reinforced concrete (SFRC) is increasingly being used for ground slab applications. The addition of steel fibres to concrete imparts significant post-cracking ductility (toughness). This ductility is used to determine a post-... WA Elsaigh - Journal of the South African Institution of...
Lightweight concrete is known for its advantage of reducing the self-weight of structures, and the areas of sectional members as well as making the construction convenient. Thus the construction cost can be saved when applied to structures such as long-span bridges and high rise buildings. Howeve...
lime-sand bricks with a low bulk density and a green blank density of >=1 kp/cm2 using a mixt. of sand, lime and water which is fed into the moulds of a compaction plant for pressing into blanks which are then hardened in a boiler. The novelty is that >=1 wt.% cement is added...
EHS thanks the Deutsche Forschungsgemeinschaft (DFG) for financial support of the CODA-project (FOR 2825).More Information Abstract Cracks are accounted as the most destructive discontinuity in rock, soil, and concrete. Enhancing our knowledge from their properties such as crack distribution, density...
The packing characteristics of the cementitious materials have great influence on the performance of a concrete mix, but there is so far no generally accepted method of measurement. Herein, a new method, called the wet packing method, is developed. It mixes the cementitious materials with water ...
This study was conducted to evaluate the effects of stocking density and monosex culture on growth, survival, yield and feed conversion ratio of freshwater prawn Macrobrachium rosenbergii in concrete tanks. Juvenile prawns with an average weight of 1.8 g were stocked into triplicate tanks at densiti...
