materials. UHSC mixture proportions were developed using local materials so that UHSC may be made more affordable to a wider variety of applications. Specifically‚ local sand with a top size of 0.0236 in. (600 μm)‚ and locally available Type I/II cement and silica fume were used in this research. Each of these material selections is seen as an improvement in sustainability for UHSC. Two mixtures (one with and one without fibers) were recommended as the UHSC mixtures. The greatest compressive strengths

study of the sorptivity‚ accomplished in mixtures of selfcompacting concrete with different types of additives and a normal concrete compacted by vibration. The self-compacting concrete mixtures present slump-flow of 650 ± 50 mm and have the same cement contents. In the self-compacting mixtures‚ were used as additives‚ fly ash‚ silica fume‚ hydraulic lime and a mixture of fly ash and hydraulic lime. A modified carboxylates superplasticiser was used to obtain a specific workability. The capillary
