Effect of internally stored water on creep of high-performance concrete
(AMER CONCRETE INST, 2008)
The effects of internally stored water on long-term deformations of high-performance concrete (HPC) were examined on 130 creep and shrinkage specimens and 750 compressive strength specimens. Creep and shrinkage were monitored ...
High-strength self-curing low-shrinkage concrete for pavement applications
(TAYLOR & FRANCIS LTD, 2010)
High-performance concretes (HPC) that are designed to possess high early strength, self-curing capabilities and low shrinkage may potentially improve rigid pavement performance. A multi-scale experimental programme examined ...
Using Isothermal Calorimetry to Assess the Water Absorbed by Fine LWA during Mixing
(ASCE-AMER SOC CIVIL ENGINEERS, 2012)
Fine lightweight aggregate (LWA) is being increasingly used for the manufacture of internally cured concrete. Internally cured concrete can be viewed as a concrete that contains fluid (water) in the pores of the LWA (or ...
Absorption and desorption properties of fine lightweight aggregate for application to internally cured concrete mixtures
(ELSEVIER SCI LTD, 2011)
Recently, substantial interest has developed in using fine lightweight aggregate for internal curing in concrete. Mixture proportion development for these mixtures requires the specific gravity, water absorption, and water ...
Assessing Lightweight Aggregate Efficiency for Maximizing Internal Curing Performance
(AMER CONCRETE INST, 2011)
Internal curing (IC), which has been extensively investigated in the last decade, has been shown to enhance hydration, diminish autogenous shrinkage, and mitigate early-age cracking due to self-desiccation in high-performance ...
Prestress losses in high performance lightweight concrete pretensioned bridge girders
(PRECAST/PRESTRESSED CONCRETE INST, 2005)
The purpose of this research was to determine the time-dependent behavior of high performance lightweight concrete and to examine how long-term behavior affects the prestress losses in high strength precast, prestressed ...
Concreto leve estrutural: substituição do agregado graúdo convencional por argila expandida
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilEngenharia CivilUTFPR, 2016-06-14)
Due to the population growth, the constructions have become vertical and the buildings even higher through the years, which made necessary new types of constructions and new materials that can help to optimize the process ...
