ABSTRACT. This paper introduces and compare Normal concrete and ultra high strength concrete about compressive strength and how to make it in Dong Nai. The compressive strength of ultra high strength concrete is 150 – 200 Mpa. Mechanical properties and applicability of the concrete with the compressive strength up to 150 Mpa in bridge structures are specially paid attentions. Ultra-High Performance Concrete (UHPC), also known as reactive powder concrete (RPC), is a high-Strength, ductile material formulated by combining potland cement, silica fume, quartz flour, fine silica sand, hith-range water reducer, water, and steel or organic fibers. The material provides compressive strengths up to 29,000 pounds per square inch (psi) and flexural strenghths up to 7,000 psi.

KEYWORDS. ultra-high performance concrete, aggregate to make ultra high strength concrete.
