· THE BEHAVIOR OF HIGH PERFORMANCE STRUCTURAL LIGHTWEIGHT CONCRETE AT ELEVATED TEMPERATURES. Results from a three year experimental study of the behavior of a highstrength (60 MPa) lightweight aggregate (LWA) concrete at elevated temperatures, including simulated hydrocarbon fire exposure, are described.
High performance lightweight concrete, HPLC, can be thought as a combination between high performance concrete and structural lightweight concrete [4]. Only some of the characteristics of HPLC have a direct relationship to initial costs. For instance, the lower dead weight of HPLC means less expense due to materials movement on site.

High Performance Lightweight Concrete By using high strength/high performance lightweight concrete in prestressed concrete bridge girders, spans of bridge girders can be extended by up to 20%. The impliions of using lightweight aggregate on prestressing losses longterm creep and shrinkage deformation should be considered.
ABSTRACT. High Performance lightweight aggregate concrete has many advantages for the construction of offshore structures. These include a high
ITEM M LIGHTWEIGHT HIGHPERFORMANCE CONCRETE FOR THIN STRUCTURAL SLABS BOTTOM FORMWORK REQUIRED 1 of 4 April 21, 1998 DESCRIPTION. Furnish and place reinforcing steel and lightweight highperformance concrete to construct thin superstructure slabs as shown in the contract plans. MATERIAL REQUIREMENTS. Use materials meeting §5572.
The paper describes an experimental program to demonstrate the feasibility of using lightweight high performance concrete (LWHPC) bridge beams and decks. These prestressed beams had a minimum 28day compressive strength of 8,000 psi and the deck concrete had 4,000 psi. The beams had maximum permeability of 1500 coulombs, and the deck concrete had 2500 .
ultra high performance concrete (UHPC) provides a new ... highcarbon metallic fibers, structural UHPC products can achieve compressive strengths up to 29,000 psi (200 MPa) and flexural ... contemporary, lightweight, colored and textured products such as chairs, ...
Lightweight structural concrete. Lightweight aggregate concretes can be used for structural appliions, with strengths equivalent to normal weight concrete. The benefits of using lightweight aggregate concrete include: Reduction in dead loads making savings in foundations and reinforcement. Improved thermal properties. Improved fire resistance.
Ultrahighperformance concrete (UHPC) was first introduced as reactive powder concrete (RPC) in the early 1990s by employees of the French contractor Bouygues. When introduced, it came in two classes: Class 200 MPa (29 ksi) and 800 MPa (116 ksi). In the, several state departments of transportation have expressed interest in introducing ...
This is a compilation of papers addressing "HighPerformance Structural Lightweight Concrete" presented October 30, 2002 at the American Concrete Institute Fall Convention in Phoenix, Arizona. This symposium was sponsored by ACI Committee 213, Lightweight
· Ultrahigh performance concrete (UHPC) is a novel construction material exhibiting enhanced mechanical and durability properties, which can lead to economical construction through reducing the crosssections of structural members with associated materials savings and lower installation and labor costs (Tang 2004).The relatively high initial cost of UHPC has restricted its .
HIGHSTRENGTH STRUCTURAL LIGHTWEIGHT CONCRETE. HIGHPERFORMANCE CELLULAR CONCRETE HighPerformance Cellular Concrete [HPCC] has all the properties of cellular concrete and can achieve MPa [8,000 psi]. Higher strengths can be produced with the addition of supplementary cementitious materials.
