, 2020 AbstractIn pursuit of reducing the dead-weight of precast concrete structures, one approach is by adopting lightweight concrete. EN 13369:2013 specifies a minimum cube compressive strength of at least 18 MPa for the lightweight concrete to be eligible for use in reinforced precast concrete products.

Effect of temperature curing on lightweight expanded clay aggregate concrete
Materials Today: Proceedings, 2021 Abstract Lightweight Aggregate Concrete is usually a mix of Lightweight Aggregates and admixtures. This paper is focused on use of Lightweight Expanded Clay Aggregate (LECA) for the development of structural Lightweight Concrete. The present investigation was carried out by replacing LECA with 30% of Normal Weight Aggregate (NWA) with different water

Crack healing in cementitious materials including test methods [PDF]
, 2020 If concrete is crack free, deleterious substances can be avoided entering the body of the material, that may corrode the rebar or encourage freeze/thaw damage. This paper examines a self healing system of cementitious materials.

The effect of concrete composition and aggregates properties on performance of concrete
Journal of Civil Engineering and Management, 2009 The properties of the hardened concrete depend on the selected raw materials: size and amount of the particles of coarse aggregate, as well as on the ratio of other components.

Autogenous shrinkage, speciality of high performance concretes [PDF]
, 2015 Autogenous shrinkage is a consequence of self dessication in pores of hardened cement paste and is, at high performance concrete significantly greater than that of the ordinary concretes, mainly due to low water to cement ratio.

Advanced Engineering Materials, EarlyView.Freeze‐drying of layered silicate is the key to get coatings with superior gas barrier. Freeze‐drying of layered silicates modified with dodecylamine (DDA) is a highly effective technique for the preparation of barrier pigments that significantly mitigate the permeation of oxygen, water vapor, and hydrogen through polymer films containing these ...

Reviews on the Properties of Aggregates made with or without Geopolymerisation Method [PDF]
, 2013 Aggregates are popular for use in concrete and lightweight concrete applications. Recent research shows that the by-product materials such as fly ash can be used as raw material in producing aggregates and lightweight aggregates.
