Polyethylene Glycol-600/expanded clay aggregate with Alccofine1203 in concrete

Materials Today: Proceedings, 2021
Abstract The present work focuses on improving the thermal and mechanical properties of concrete using polyethylene Glycol-600/Expanded Clay Aggregate (ECA) with Alccofine1203. Immersion method was adopted with two different standards; ECA immersed at room temperature and higher temperatures (30 °C, 40 °C & 50 °C) for 8 h.

Mechanical characterization of concrete produced with recycled lightweight expanded clay aggregate concrete

Journal of Cleaner Production, 2015
Abstract In this paper the main mechanical properties of concrete produced with recycled aggregates obtained from crushing both structural and non-structural lightweight concrete are characterized. Various concrete mixes with replacement ratios of 20%, 50% and 100% of two types of coarse lightweight aggregates (LWA) by recycled lightweight concrete ...

Long-term behaviour of concrete produced with recycled lightweight expanded clay aggregate concrete

Construction and Building Materials, 2014
Abstract In this paper some of the main long-term properties of concrete produced with recycled aggregates obtained from crushing both structural and non-structural lightweight concrete (LWC) are analysed. The properties studied are drying shrinkage, capillary and immersion absorption, and carbonation and chloride penetration resistance.

Search for Ranking Approaches of Expanded Clay Concrete Quality Criteria

Materials Science Forum, 2019
The article is devoted to ranking of quality criteria for multiparameter, multicriteria production technology of lightweight concrete depending on their significancy using fractal formalism. The proposed approach allows to determine the operation area of stability of the physicomechanical properties of expanded clay concrete with preset technology ...

Drying of lightweight concrete produced from crushed expanded clay aggregates

Cement and Concrete Research, 1996
When crushed lightweight aggregates are used in lightweight aggregate concretes very small water amounts evaporate from the concrete even in a dry environment. It is shown that a large portion of the free batch water is absorbed into the pore structure of the crushed aggregates. The relative humidity in concrete pore structure diminishes faster than in

Deformability of dispersed reinforced expanded clay concrete under load

Building and Reconstruction
The article is devoted to the study of the deformation and destruction characteristics of expanded clay concrete dispersively reinforced with fibers. The article presents the test results of expanded clay concrete samples reinforced with high-modulus basalt fiber, as well as low-modulus synthetic micro- and macrofiber.

Production of structural lightweight concrete with expanded clay aggregate

2009
In this study, the manufacturing possibility of the high strength lightweight concrete having different amount of the cement by using expanded clay aggregate and its physical and mechanical properties were investigated. For this purpose, concrete mixtures used expanded clay aggregate and natural sand was designed.
