Reactive powder concrete with lightweight aggregates

Construction and Building Materials, 2020
Abstract The paper presents test results of lightweight concretes obtained by introduction of lightweight aggregates: Pollytag, expanded clay aggregate and expanded polystyrene beads (EPS) in quantity from 30 vol% to 60 vol% to the RPC mix. It was demonstrated that addition of the expanded clay aggregate allowed to obtain lightweight RPC with the ...

Durability of lightweight concretes with lightweight fly ash aggregates

Construction and Building Materials, 2011
Abstract This paper presents the effects of aggregate properties such as strength, porosity, water absorption, bulk density and specific gravity on the strength and durability of lightweight fly ash aggregate concrete (LWAC). The influence of properties of four aggregates (sintered lightweight fly ash aggregates, cold-bonded lightweight fly ash ...

EFFECTS OF LIGHTWEIGHT AGGREGATES ON AUTOGENOUS DEFORMATION IN CONCRETE

2007
To reduce autogenous deformations in high performance concrete at early ages, dispersed saturated lightweight aggregates (LWAs) are used as water reservoirs. For this purpose, in a concrete with low water cement ratio, normal aggregates have been replaced by natural LWAs at size fractions of 2-4mm or 4-8mm at three different volume fractions such as 10,

Lightweight aggregates for structural concrete

1976
This monograph is concerned with lightweight aggregates that can be used in structural lightweight concrete; namely those produced from clay, shale, slate, blast furnace slag, and fly ash. The clays, shales and slates are the most widespread of raw materials, although slate is not used in Canada.

Effect of presoaking degree of lightweight aggregate on the properties of lightweight aggregate concrete

Computers and Concrete, 2017
This study aimed at exploring the effect of presoaking degree of lightweight aggregate (LWA) on the fresh and hardened properties of concrete. Two series (i.e., Series A and Series B) of concrete mixes that were made of LWA with different moisture states were prepared.
