Advances in the science of concrete materials have led to the development of a new class of cementitious composites called ultra-high performance concrete (UHPC). The links above will direct you to pages detailing UHPC projects‚ bridges with UHPC components‚ articles that focus on UHPC research‚ and the main contact at Turner-Fairbank Highway Research Center (TFHRC) for UHPC The mechanical and durability properties of UHPC make it an ideal candidate for use in developing new solutions to pressing

Deierlein‚ Stanford University; Jerome F. Hajjar‚ Northeastern University For decades‚ the goal of seismic engineers has seemed straightforward: Prevent building collapse. And so they add steel braces to a skyscraper’s skeleton or beefier rebar to concrete shear walls. After absorbing the brunt of seismic shaking‚ however‚ the compromised structures often must be demolished. “The building‚ in a sense‚ sacrifices itself to save the occupants‚” says Gregory Deierlein‚ a Stanford University civil and

high-efficiency equipment. It is the latest researched results basing on Germany technology. The machine is professional in producing qualified sand and stone for highway‚ high-speed railway‚ high building‚ city project‚ hydropower dam constructions‚ and concrete mixing plant. It is widely used in sand making and stone reshaping industry. Vertical shaft impact crusher also know as sand making machine is applied widely for the powder process of mineral product including mental and non-metal ore‚ fireproof

It can be used to form relatively thin‚ compound curved sheets to make hulls for boats‚ shell roofs‚ water tanks‚ etc. Ferro concrete has relatively good strength and resistance to impact. When used in house construction in developing countries‚ it can provide better resistance to fire‚ earthquake‚ and corrosion than traditional materials‚ such as wood‚ adobe and stone masonry

usually a mixture of metal oxides and silicon dioxide. Ground granulated slag is often used in concrete in combination. Ground granulated slag reacts with water to produce cementations’ properties. Concrete containing ground granulated slag develops strength over a longer period‚ leading to reduced permeability and better durability. Since the unit volume of Portland cement is reduced‚ this concrete is less vulnerable to alkali-silica and sulfate attack. Hongxing Heavy Industry machinery recommend

Since the use of a concrete overlay‚ called as whitetopping‚ is a relatively new concept in Hot Mix Asphalt (HMA) pavement rehabilitation in India. Portland cement concrete (PCC) overlay on an existing bituminous pavement is commonly known as whitetopping. The principle purpose of an overlay is either to restore or to increase the load carrying

INTRODUCTION 1.1 THE DESIGN PROCESS: The entire process of structural planning and design requires not only imagination and conceptual thinking but also sound knowledge of practical aspects‚ such as recent design codes and bye-laws‚ backed up by ample experience‚ institution and judgment. It is emphasized that any structure to be constructed must satisfy the need efficiency for which it is intended and shall be durable for its desired life span. Thus‚ the design of any structure is categorizes
