Effects of LECA Content on the Behavior of Steel Fiber-Reinforced Geopolymer Concrete at High Temperature

Civil and Environmental Engineering
This paper examines how steel fiber and the amount of lightweight expanded clay aggregate (LECA) affect the mechanical and microstructural properties of geopolymer concrete (GPC) made from fly ash after being heated.

Mineral fertilization reduces the drought resistance of soil multifunctionality in a mountain grassland system through plant-soil interactions

Peer Community Journal
Increasing droughts threaten soil microbial communities and the multiple functions they control in agricultural soils. These soils are often fertilized with mineral nutrients, but it remains unclear how this fertilization may alter the capacity of soil ...

EXPERIMENTAL STUDY ON LIGHTWEIGHT CONCRETE USING LECA MATERIALS

International Journal of Advanced Research
This study investigates the feasibility of incorporating Lightweight Expanded Clay Aggregate (LECA) materials into concrete to produce lightweight concrete with improved mechanical properties. The experimental approach involves varying proportions of LECA aggregate in concrete mixes and assessing their compressive strength, density, workability, and ...

Investigations on self compacting concrete using fly ash and light expanded clay aggregates

Zaštita Materijala
Compaction and curing both are equally important to achieve the desired strength and durability of concrete. To make concrete with a better surface finish, improved strength, and durability, it is essential to impart self compacting ability to concrete ...
