Schmidt Test Hammer Rebound Hammer test is a Non-destructive testing method of concrete which provide a convenient and rapid indication of the compressive strength of the concrete. The rebound hammer is also called as Schmidt hammer that consist of a spring controlled mass that slides on a plunger within a tubular housing. The operation of […]
Concrete Asphalt Abstract Polymer concrete (PC) is considered a promising repair material for asphalt pavement, since it has excellent paving performance and water stability. Although the mechanical properties of PC have been widely researched, the fatigue behavior of PC under traffic loads was still poorly understood. To predict the fatigue life and optimize the material […]
Compressive strength of concrete Out of many test applied to the concrete, this is the utmost important which gives an idea about all the characteristics of concrete and Compressive Strength of it. By this single test one judge that whether Concreting has been done properly or not. Compressive strength of concrete depends on many factors […]
Elastic Modulus System VŠCHT, the University of Chemistry and Technology, Prague, is the latest institution to purchase a MATEST elastic modulus system for its new cutting-edge laboratory. “More and more important universities, laboratories and companies around the world are using MATEST elastic modulus systems for tests which meet international standards,” according to Alessandro Peretti, MATEST’s […]
Los Angeles Abrasion Overview The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA. The standard L.A. abrasion […]
Asphalt Stripping Description The loss of bond between aggregates and asphalt binder that typically begins at the bottom of the HMA layer and progresses upward. When stripping begins at the surface and progresses downward it is usually called raveling. Although the displacement of asphalt on the aggregate particle surface by water (stripping) is a complex […]
Self Healing Concrete The green technology embeds self-activating bacteria into concrete to make it self-healing, but will it win over a risk-averse construction industry? Of all the carbon emitters that surround us every day it’s easy to overlook one of the most ubiquitous: concrete. The material that builds our buildings, paves our roads and spans […]
