According to the database assembled in this study, a minimum confinement stiffness ratio ρKe of 0.016 is required to produce a strength recovery for square columns, where ρKe is the effective confinement stiffness ratio for square or rectangular columns. (5)ρKe=2ksEftf(fco′/εco)De (6)...
The water/cement ratio was 0.4, as specified by the Wisconsin Department of Transportation's standard specifications for concrete Grade A. No other admixtures or additives were used. The specimens were stripped from their plastic mold two days after casting of the concrete and were then wet cured...
The substantial rise in the tension-to-compression ratio suggests a reduced likelihood of catastrophic failures for these cement-based materials, which serves as a significant factor when considering the utilization of areca husk fiber in concrete mixtures, provided that the strength requirements are ...
and water. The general ratio is 1 part Portland cement to 2 parts sand, with enough water to achieve a thick, but workable, consistency. However, for most small projects, pre-mixed concrete can save time and provide more consistent results. ...
ratio and arrangement were made such as (1) impulse and absorbing the energy of the slab were not significantly influenced with variation in reinforcement arrangement and its ratio, and (2) mode of failure and damage pattern were influenced mainly by the arrangement of the reinforcement(s). ...
one often wonders if the age of concrete affects the drilling process. This query is particularly prevalent among Aucklanders planning renovations or additions to their homes.Auckland concrete cutting specialistsfrequently address such concerns, and this article aims to shed light on the matter, discuss...

Poisson’s ratio, modular ratio, unit weight, overall durability, tensile strength, compressive strength, and characteristic strength are important to understand. In short, well-maintained concrete slabs can last forever if prepped and poured correctly. If you’re interested in learning more about con...
Carbon capture and utilization for concrete production (CCU concrete) is estimated to sequester 0.1 to 1.4 gigatons of carbon dioxide (CO2) by 2050. However, existing estimates do not account for the CO2 impact from the capture, transport and utilization
