Exploring the effect of low-heat cement on early-age thermal cracking resistance of roller-compacted concrete

open access: yesJournal of Materials Research and Technology, 2022
In this paper, the early-age thermal cracking behavior of roller-compacted concrete prepared with low-heat cement (LHC) was investigated using a concrete temperature stress testing machine. The test results show that under the same restraint degrees, the

Post-cracking tensile behaviour of steel-fibre-reinforced roller-compacted-concrete for FE modelling and design purposes [PDF]

open access: yesMateriales de Construccion, 2017
Fracture of steel-fibre-reinforced-concrete occurs mostly in the form of a smeared crack band undergoing progressive microcracking. For FE modelling and design purposes, this crack band could be characterised by a stress-strain (σ-ε) relationship.

Expounding structures of roller compacted concrete dam specimens by means of hard conventional X-ray inspection [PDF]

open access: yesHeliyon, 2019
A simple solution to improve the contrast between the different concrete composites in X-ray imaging (radiography and tomography) of a highly compressed composite sample of real size roller compacted concrete (RCC) specimens is presented. This is made by

A comparison of flexural strengths of polymer (SBR and PVA) modified, roller compacted concrete. [PDF]

open access: yesData Brief, 2015
This brief article aims to reveal the flexural performance, including the equivalent flexural strength of PVA (Polyvinyl Alcohol) modified concrete by comparing it primarily with that of SBR (Styrene Butadiene Rubber) concrete.

Relationship between compressive and tensile strengths of roller-compacted concrete

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2018
The abstract roller-compacted concrete (RCC) is a zero slump concrete comprising the same materials as that of conventional concrete with different proportions. The RCC must be compacted to reach its final form.

COMPARATIVE CHARACTERISTICS OF THE TECHNOLOGIES OF ARRANGEMENT OF RIGID PAVEMENT LAYERS FROM ROLLER-COMPACTED CONCRETE MIXTURES AND TRADITIONAL PAVING CONCRETE MIXTURES [PDF]

open access: yesДороги і мости, 2022
Introduction. Paving roller-compacted concrete is a multi-component, artificially obtained stone-like material that is obtained from a paving roller-compacted concrete mixture, which is characterized by increased requirements for tensile strength at ...

Prospects of application of roller compacted concrete in hydro schemes of Ukraine [PDF]

open access: yesE3S Web of Conferences, 2021
Prospects of application of roller compacted concrete in hydro schemes of Ukraine are considered. The number of dams erected with application of roller compacted concrete is growing year after year in the world. Roller compacted concrete is an especially

Investigation of the Effect of Various Mixing Designs and Macro Textures on the Skid Resistance of Roller Compacted Concrete Pavement Surface [PDF]

open access: yesپژوهش‌های زیرساخت‌های عمرانی, 2021
The purpose of this study is to investigate strategies to improve the skid resistance of roller-compacted concrete. Since the main weakness of roller-compacted concrete is the lack of pavement macrotexture, in this study, three types of macro textures, 1-
