A concrete core test is a very famous and well-established testing method for the compressive strength of the hardened concrete. Concrete core testing enables visual inspection of the interior regions of the concrete member which is also related to strength estimation. Concrete coring also enables to evaluate other properties of…
Concrete Slump Test for Workability – Types of Slumps, Procedure and Acceptance Criteria of Slump Test
What is Slump Cone Test? A Slump test or Concrete slump test is to determine the workability or consistency of the concrete mixture prepared in the laboratory or at the construction site during the progress of work. The concrete slump cone test is used for the measurement of a property…
What is Cellular Lightweight Concrete? Types, Advantages and Applications of Cellular Lightweight Concrete
What is Cellular Lightweight Concrete (CLWC)? Cellular lightweight concrete (CLWC) is a mixture of cement, water, and pre-formed foam. This material is mixed to a pumped into any void and specified density. The fundamentals are simple, but the application and the ability to mix properly and at high production rates…
What is Bacterial Self Healing Concrete? Its History, Application, Advantages, and Disadvantages
Bacterial self-healing concrete is an innovative technology allowing repairing open micro-cracks in concrete by calcium carbonate (CaCO3) precipitation. This biotechnology improves the durability of the structure. Abstract Nowadays alternative approaches in construction technology are evolving rapidly in a bid to crucial the environmental hazards and low sustainability imparted by the…
Pervious Concrete
Preamble At many projects, waterlogging at parking & walkways is the major issue especially during monsoon as pavements & floors are normally impermeable. This results in a considerable amount of investment in repairs & providing a stormwater drainage system that may get clog during peak overflow situation. Besides this, there…
Architectural Concrete
Almost every Architect and Developer wants their building and structures to be somewhat unique and unmistakable…. And nowadays Green. One special subset of concrete is called architectural & decorative, which refers to concrete that provides an aesthetic finish and structural capabilities in one. Because of its versatility, concrete offers immeasurable…
Significance of Water to Cement ratio
INTRODUCTION This article is devoted to one of the most, if not the most important factor required to be specified, controlled, and insisted upon while manufacturing concrete. The significance of the Water to Cement ratio (W/C) has been understood by very few concrete producers. Many feel that controlling W/C means…
CONCRETE – LET’S SEE AS A FAMILY OF MATERIALS
INTRODUCTION Concrete consists of different material which has different functions but combines together to achieve workability and cohesiveness (in plastic stage) and give the desired shape, surface finish, strength, and durability (in hardened stage). Cement and cementitious materials (mineral admixtures) are fine powders which react with water to form the…
