Abstract:-There has been continuous demand for materials with higher compressive strength for various civil engineering applications. Reactive powder concrete (RPC) has been developed to overcome the weakness of most high strength concrete available with compressive strength in the range of 60-100 MPa. RPC was developed from a special combination of constituent materials such as Portland cement, silica fume, quartz flour, fine silica sand, high-range water-reducer, water and steel fibers wherein attempts have been made to remove the coarse aggregate particles to make a very strong mortar with a very low water cement ratio. This paper presents a state of the art report reviewing the research in the area of the development of RPC, highlighting the enhanced performance in the mechanical properties of RPC in direct application of its use in structural members requiring high standards of strength coupled with superior performance and durability.

“…It was chosen to be 1230 kg/m 3 . Many researchers like (Lee et al, 2006(Lee et al, , 2007 [21,22] and (Reeves, 2004) [23] choose the fi ne sand content to be 1020kg/m 3 but they use quartz powder of 210 kg/m 3 content. In this research we use El-Arish sand with its grading without adding any quartz powder to make the fi nal product of our locally cast reactive concrete more economical so that, 1230 kg/m 3 of sand was chosen.…”

The used super-plasticizer content was chosen to be one tenth of the average cement content which was 750 kg/m 3 which mean 75 kg/m to the researches done by (Lee et al, 2006(Lee et al, , 2007 [21,22] while other researchers like (Richard and Cheyrezy, 1995) [7] chose the super-plasticizer content to be 0.02 of the cement content but (Jungwirth, 2002) [24] use 0.04 of the cement content while (Matte and Moranville, 1999) [14] and (Yazici et al, 2009) [25] preferred to use about 0.066 of the cement content. In this research the higher content was chosen to make the concrete more workable and to decrease the compaction effort while casting.…”

In this research reactive powder concrete (RPC) was prepared using sand from North Sinai. The mechanical properties of locally cast RPC were investigated and evaluated by studying the effects of using different cement and silica fume contents and new steel fi bers' aspect ratios as reinforcement for RPC. Specimens' preparation, curing regimes and testing procedures to evaluate the compressive strength, the modulus of elasticity, the indirect tensile strength and the fl exural strength were discussed. A compressive strength of 154.5MPa, indirect tensile strength of 11.98MPa, modulus of elasticity of 45.1GPa and fl exural strength of 30.26MPa have been achieved for reinforced RPC contains 800 kg/m 3 cement content and silica fume content 30% of cement weight. The test results showed some improvements by increasing cement and silica fume contentsas well as adding steel fi bers on the compressive strength, modulus of elasticity and indirect tensile strength.

“…The microstructure and thus engineering properties of highperformance (DSP) cementitious materials can be improved by steam or high-pressure steam curing, which benefit pozzolanic reactions. Based on a review of the literature on DSP highperformance cementitious materials (Guerrini G.L., 2000;Shannag M.J., et al, 1991;Sun G.K. and Young J.F., 1993;Sun G.-k. and Young J.F., 1993;Beaudoin J.J., et al, 1994;Richard P. and Cheyrezy M., 1995;Cheyrezy M. et al, 1995;Shannag M.J. et al, 1996;Young J.F., 1996;Roux N. et al, 1996;Zanni H., et al,1996;Feylessoufi A. et al,1996;Shannag M.J. et al, 1997;Hu A., et al,1999;Shannag M., et al, 1999;Zivica V., 1999;Matte V. and Moranville M., 1999;Shannag M.J. and Hansen W., 2000;Camilleri J., et al,2001;Moranville-Regourd M., 2001;Collepardi M., et al, 2002;Morin V., et al,2002;Badanoiu A. et al, 2003;Bayard O. and Pie O., 2003;Chan Y.-W. and Chu S.-H., 2004;Washer G. et al, 2004;Lee M.-G. et al, 2007;Wong A.C.L. et al,2007), the cementitious mortar introduced in Table 1 was selected for evaluation of the merits of oxidized carbon nanofibers in cementbased matrices.…”

Cementitious materials, especially those with higher compressive strengths, provide relatively low toughness, tensile strength and strain capacity, and are susceptible to cracking under load and restrained shrinkage effects. These drawbacks were overcome through development of multiscale reinforcement systems comprising carbon nanofibers and microfibers for high-strength cementitious mortars. Multi-scale reinforcement of the high-performance mortar produced significant gains in the flexural strength and toughness, and abrasion and impact resistance. Microstructural investigations were also conducted in order to provide insight into the structure and failure mechanisms of high-performance cementitious mortars with multi-scale reinforcement.
