Development of Lightweight Aggregate Concrete

STRUCTURE magazine | Improved Bridge Deck Performance with

The effect of lightweight aggregate on the cracking tendency of bridge deck concrete was evaluated using cracking-frame testing techniques. Cracking frames measure the restrained concrete stress development due to thermal and autogenous shrinkage effects from setting until the onset of cracking under conditions that match those of in-place

Parametric assessment of stress development and cracking

The pre-wetted lightweight aggregate serves to increase relative humidity inside concrete, thereby the reducing capillary tension and the associated residual stress development in concrete [20, 21]. Shin et al. [22] have also shown that the use of aggregates with reduced stiffness can improve the shrinkage cracking resistance of

Development and characteristics of ultra high-performance

By means of incorporating silica fume and high-range water reducer, structural high strength lightweight aggregate concrete (HSLAC) could be produced, which typically exhibits compressive strength higher than 40 MPa and density less than 2000 kg/m3 [,, ]. The investigations on HSLAC have attracted many researchers' interests.

Mechanical Properties of Chopped Basalt Fiber-Reinforced

In this study, an experimental investigation was conducted on the mechanical properties of lightweight aggregate concrete (LWAC) with different chopped fibers, including basalt fiber (BF) and polyacrylonitrile fiber (PANF). The LWAC performance was studied in regard to compressive strength, splittin

lightweight concrete - Post-war building materials

Lightweight concrete is a collective term for different types of concrete which are all characterized by a low specific weight. The reduced density is achieved by adding specific ingredients to the mixture or by means of special production techniques, resulting in a weight decrease from 2.000 or 2.500 kg/m³ for 'ordinary' concrete to approx. 500 []

Lightweight Aggregate Concrete (Building Materials Science

Microstructure development and its relation to the durability properties of LWAC generally are not highlighted in the literature. The development of bonds, the microstructure with different binder systems, and different types of lightweight aggregates are explained. They show how lightweight aggregate concrete differs from normal weight concrete.
