dc.description.abstract |
High strength concrete offers many advantages in the construction of high-rise
buildings and bridges. In many countries, concrete strengths higher than 40 MPa
are widely produced on commercial basis using normal aggregates and cement.
Use of chemical and mineral admixtures has become an integral part of producing
high strength concretes.
At present, normal strength concrete is used in reinforced concrete construction in
Sri Lanka. As the current trend for high rise buildings and the use of precast
concrete is expected to increase, there wall be a greater demand in Sri Lanka for
high strength concrete. A study was undertaken at the University7 of Moratuwa to
examine various approaches for developing high strength concrete and to achieve
concrete strengths higher than 40 MPa using only locally available materials. A
high range water reducing admixture presently available in the market was used to
reduce water/cement ratio of the concrete mixes while achieving sufficient
workability. Compressive strengths up to 65 MPa w7ere achieved using locally
available cement, sand and coarse aggregates with moderate dosages of water
reducing admixture. |
