Researchers have, for the first time, used a 'micropillar compression' technique to characterize the micro-scale strength of cement, allowing for the development of cement with desirable strength ...

In the global construction quality assurance and materials testing industry, Zhuozhou Tianpeng Imp. and Exp. Trade Co., Ltd. has emerged as a top concrete testing equipment manufacturer, recognized ...

Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...

Nondestructive testing of concrete strength encompasses a suite of techniques designed to evaluate in situ mechanical properties, structural integrity and durability of concrete elements without ...

When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...

Concrete is an essential construction material that is used globally. Combining coring and rebound surveys provides the most efficient and cost-effective method of assessing in situ concrete strength, ...

Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...

This image shows a representative cement micropillar sample imaged by scanning electron microscope. Samples like this one are key to the use of a 'micropillar compression' technique to characterize ...

In my previous column, I discussed double-shear testing of a single fastener (see “Editor's Picks,” at right). But fasteners also can be subjected to single-shear loading — our subject this time — and ...
