Ppt On Lightweight Concrete

Shotcrete, also known as gunite or sprayed concrete, is a process where concrete or mortar is pneumatically projected at high velocity onto a surface. There are two main types of shotcrete - dry process and wet process. Dry process involves placing dry ingredients into equipment and adding water at the nozzle, while wet process thoroughly mixes ...

4. Lightweight concrete contains no aggregate larger than sand, lime, thermal ash, synthetic fiber, cement, aluminum powder and water as binding agent. When AAC is mixed and cast in forms, several chemical reactions take place that give AAC its light weight (20% of the weight of concrete) and thermal properties. Therefore, lightweight concrete is quite light and …

11. Structural light weight concrete: Concrete which is light weight and has sufficient compressive strength. 28 days compressive strength of more than 17Mpa and 28 days dry density not exceeding 1850 kg/m3. Generally has normal fine aggregates and lighter coarse aggregates. Workability is less due to water absorption by the aggregates. Drying shrinkage is more and …

What is Lightweight Concrete? Lightweight concrete is a specialized concrete mixture made with lightweight coarse aggregates, and sometimes lightweight fine aggregates, instead of traditional aggregates. This type of concrete possesses an in-place density (unit weight) typically ranging from 90 to 115 lb/ft³ (1440 to 1840 kg/m³), in contrast ...

Two formulations were tested: one using spherical EPS beads and another using ground EPS waste material. Tests found that while the waste material concrete had lower compressive strength and elastic modulus than the bead concrete due to higher air content, both formulations produced structurally viable lightweight concrete.
