Strength of slender reinforced concrete walls [PDF]

open access: yes, 1983
This study is concerned with the behaviour of single span slender reinforced concrete members with depth/span ratios equal to and larger than 1. A series-of deep panels with depth/span ratios between I and 4 was studied experimentally.

Development of high performance concrete using combinations of mineral admixtures. [PDF]

open access: yes, 1995
Cement replacement materials are by-products used to produce high performance concrete. Published data on the effects of combinations of mineral admixtures in concrete on the microstructural and performance-related properties under different ...

Punching shear strength of steel fibre reinforced lightweight concrete slabs. [PDF]

open access: yes, 1981
One of the problems in slab-column connections is the punching shear failure at over loads. Such failures are sudden and catastrophic, and are undesirable since they do not allow an overall yield mechanism to ...

Response surfaces for compressive strength of concrete

open access: yesConstruction and Building Materials, 2013
The aim of total quality management (TQM) is to offer satisfactorily high quality products to customers for providing increased productivity and decreased costs. Various methods are used for process improvement, development and optimization. In ready mixed concrete production, the number and the variations of effect parameters can be reduced using ...

SIZE EFFECT IN COMPRESSIVE STRENGTH OF CONCRETE

open access: yesTransactions of the Architectural Institute of Japan, 1977
Abstract Three series of experiments were carried out to examine the effect of the size and type of aggregate on the size effect in the compressive strength of concrete from the standpoint that it may result from the geometrical heterogeneity of concrete system.

Influence of Inertia on the Dynamic Compressive Strength of Concrete

open access: yesMaterials, 2022
The rate sensitivity of concrete material is closely related to the inertia and viscous effects. However, the effect of inertia on the dynamic strength of concrete remains unclear. In this paper, digital image correlation technology was applied to study the strain variation of dry and saturated concrete with different loading rates.

Modelling the compressive strength and thermal properties of foam concrete [PDF]

open access: yes, 2017
Foam concrete has attracted attention worldwide because of its light weight and enhanced insulating properties as a building material. Pore features in foam concrete play an important role in affecting its compressive strength and insulation properties ...

Evaluation of the use of steelmaking slag as an aggregate in concrete mix: A factorial design approach [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2017
Slag is investigated towards its potential use as an aggregate in concrete mix production. Full factorial design methodology is applied to study the effect of two process input variables, namely: slag as coarse aggregate and slag as medium aggregate on ...

USES OF DRY VINASSE AS A FRIENDLY ENVIRONMENTAL MATERIAL TO IMPROVE PROPERTIES OF CEMENT MORTAR AND CONCRETE [PDF]

open access: yesJES: Journal of Engineering Sciences, 2020
This study aims at using the sugar by-product (dry vinasse), as one of the concrete production requirements, instead of getting rid of them in vain. Dry vinasse was obtained by drying liquid vinasse at 250 ° C.

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.
