Choosing the Right Lubricants for Different Industrial Machinery

by
Choosing right lubricant for different machineries

Selecting the most appropriate lubricant is an important part of keeping industrial equipment operating reliably. While choosing the lubricants consider applications, machinery types, and operating environments in mind. Of course, there is no single lubricant that suits every conceivable industrial application. So, organisations cannot depend on “just any” general-purpose lubricant for all situations, given the … Read more

Bend and Rebend Test for Steel Rebar (IS 1786 & IS 1599)

by
Bend and Rebend Test on Steel Rebar as per IS 1786 and IS 1599

Steel is considered to be one of the vital construction materials. The process of construction involves the bending of steel to a particular form. Consequently, it is important to check the ductility of the steel, which is the ability to deform under applied pressure. Bend and Rebend Test This test procedure is used to check … Read more

How to Correlate Rebound Number with Concrete Strength

by
How to establish relationship between rebound number and concrete strength

Establishing a reliable relationship between rebound hammer numbers and the compressive strength of concrete is a crucial aspect of quality control in construction projects. This correlation serves as a valuable tool for rapid, non-destructive assessment of concrete strength in both existing and under-construction structures. The rebound hammer test offers a quick and cost-effective method to … Read more

Sustainability of Concrete: How Can We Make Concrete More Sustainable?

by
Sustainability of Concrete How to make concrete more sustainable

Sustainability of Concrete Concrete is everywhere. From foundations and retaining walls to bridges, dams, high-rise buildings, industrial plants and roads, modern infrastructure would be almost impossible to imagine without it. But concrete has a sustainability problem. The issue is not really concrete itself. The biggest environmental impact comes from the cement used to make concrete—particularly … Read more

How to Improve Construction Productivity by 30%: A Guide by CIB

by
How to improve construction productivity by 30 percent

Introduction to the 30% Productivity Target For many years, the construction industry has faced a major challenge. Projects often run over budget. They also take longer than planned. In 1994, Sir Michael Latham published a famous report called Constructing the Team. In this report, he suggested a bold goal. He stated that the construction industry … Read more

Stop Guessing Construction Productivity—Use the Activity Sampling Method Instead

by
Activity sampling method to measure construction productivity

Activity Sampling Method to Measure Construction Productivity In the construction business, managing efficiency is a major key to financial success. However, construction projects face unique challenges. Unlike a factory, a construction site is not a controlled environment. Assembly line workers repeat the exact same task in a stable workspace. In contrast, construction workers face hundreds … Read more

How to Determine the Optimum Dosage of Superplasticizer

by
How to determine optimum dosage of superplasticizer using marsh cone test

Determining the optimum dosage of a superplasticizer is essential for achieving the desired workability, strength, and durability of concrete while avoiding unnecessary admixture consumption. Two of the most widely used laboratory methods for this purpose are the Marsh Cone Test and the Mini Slump Cone Test. In this article, you will learn both methods step … Read more

Dry Material (Solid) Content Test of Chemical Admixtures

by
Solid content test of chemical admixture

Solid Content Test of Admixture Chemical admixtures have become an essential component of modern concrete, particularly when high workability is required without increasing the water content. Depending on the product, admixtures are supplied either as liquids or as powders. Solid content of admixture impacts its properties. Measuirng solid content helps in following ways. Test Summary … Read more

Strength Activity Index Test for Pozzolanic Material

by
Strength Activity Index Test for Pozzolanic Materials

Strength Activity Index (SAI) Test (ASTM C311/C311M) Ordinary Portland Cement (OPC) production is highly energy-intensive and contributes significantly to carbon emissions. To reduce cement consumption and improve sustainability, supplementary cementitious materials (SCMs) are incorporated into concrete. Many of these materials exhibit pozzolanic properties, meaning they react with calcium hydroxide [Ca(OH)₂], a by-product of cement hydration, … Read more

Silica Fume (Microsilica) in Concrete: Benefits, Working Mechanism, Dosage, Challenges

by
Silica fume of Microsilica in concrete

Concrete is no longer just a mixture of cement, sand, aggregates, and water. Modern structures such as high-rise buildings, long-span bridges, marine structures, metro projects, and industrial plants demand concrete that is stronger, denser, and far more durable than conventional concrete. One material that has completely changed the way high-performance concrete is produced is silica … Read more
