The main principle of developing reactive powder concrete is to improve the microstructure by compacting density and increasing toughness. To achieve this principle very high-grade cement is used together with pozzolanic materials. The research was conducted to study the effect of the water-cement ratio on the mechanical properties of reactive powder concrete with marble powder as constituent materials. Trial mixes were prepared using cement, sand, silica fume, marble powder, and super-plasticizer. A mix ratio of 1.0:1.1:0.2:0.1:0.03 was adopted with water-cement ratio of 0.18, 0.20, and 0.22. Concrete cylinder of size ∅10 cm × 20 cm and the concrete beam of size 10 cm × 10 cm × 35 cm were cast and cured in steam curing at 95 °C for 4 h and tested to study the compressive strength, modulus elasticity, splitting strength, and flexural strength in relation to the water-cement ratio. The results indicate that reduced water-cement ratio from 0.22 to 0.18 increases the compressive strength, modulus elasticity, splitting strength, and flexural strength. Using a lower water-cement ratio for the mixing process is difficult to handle, so this research recommended a 0.20 water-cement ratio to produce reactive powder concrete with optimum mechanical properties.
