Concrete Research Laboratory
The Concrete Research Laboratory is equipped to study basic properties of concrete constituent materials and fresh, hardening and hardened concrete. This laboratory is one of the newest and most fundamental laboratories of the Building Technology research activities. It was established in the year 2009, and since has undergone numerous upgrading and modifications.
Over the years, this laboratory serves as the center of operations for fabrication and quality control of all concrete specimens and samples required for research and studies. It has facilitated research and testing on conventional and advanced construction materials, such as cement, plain and reinforced concrete, bricks, pozzolanas, industrial byproducts, inhibitors, coating, chemical admixtures, repair materials, and polymer composite materials.
Several research studies such as concrete quality assessment of commercial and industrial buildings, fiber mesh concrete evaluation, At large, many related research and studies on concrete durability assessment have been successfully studied in this laboratory. One of the ongoing features of this laboratory is the continuous service requests for building materials evaluation and in-site evaluation of structures as well as in-house studies to evaluate the performance of building materials.
Equipment and Facilities:
The concrete laboratory has facilities for:
- Tools and apparatus for testing and evaluation of physical and chemical properties of sand aggregates and cement.
- Tools apparatus and molds for preparation and testing of standard concrete specimens.
- 200 kN compression and flexural strength testing machine with data acquisition system.
- Tiles testing machine.
- Non-destructive testing apparatus.
- Environmental chamber for curing and maturity of concrete specimens.
- Drying and high temperature ovens.
- Normal and accelerated testing facilities.
- Purpose: Researchers in the Concrete Laboratories evaluate new test methods, conduct concrete materials research, develop mixture design and analysis procedures for concrete pavements, and provide concrete forensics.
- Laboratory Description: This laboratory is comprised of five components. These include an Aggregate Materials and Sample Preparation room, and a Curing Room as well as facilities for evaluating plastic concrete properties along concrete curing and volume change; concrete durability, including freezing and thawing and alkali-silica reaction; and mechanical properties, including strength and modulus of elasticity.
- Laboratory Capabilities: Facilities exist for the preparation of aggregate samples for concrete and the preparation of hardened cement paste, mortar, or concrete specimens for testing and analysis, for batching and mixing cement paste, mortar, and concrete; and for performing tests on fresh (plastic) cement paste, mortar, and concrete. A Curing Tank is available for curing of concrete specimens under standard or other controlled conditions and assessment of curing-related properties, such as degree of hydration, maturity, and shrinkage. The Concrete Durability Laboratory provides facilities for investigating the effects of chemical and environmental exposure on concrete. It is equipped to assess, alkali-aggregate reaction; sulfate attack; chloride penetration; freezing, thawing, and thermal effects. The Mechanical Properties Laboratory provides facilities for testing the mechanical properties of concrete, steel, and composites. A Petrographic Laboratory is available for preparing and conducting petrographic and microscopic investigations of aggregate, Portland cement concrete, and asphalt concrete.
- Laboratory Equipment: The Aggregate Materials and Sample Preparation Laboratory equipment includes two rock crushers, a pulverizer, a vibrating screen, standard sieves, a Video grader (for automated sizing and shape analysis of aggregate), two drum mixers and a two-cubic-foot pan mixer for mixing concrete, mortar and paste planetary mixers, a high shear paste mixer, VeeBee, Air Void Analyzer, The Mechanical Properties Laboratory equipment includes one servo controlled universal testing machines with capacities ranging up to 200 kN and a compression testing machine.
- Laboratory Services: The Concrete Laboratories provide support in the following areas: investigating the properties and performance of Portland cement concrete and its component materials (cement, aggregate, supplementary cementitious materials (SCMs) admixtures, etc.); evaluating and developing new or improved equipment and procedures for assessing properties and performance of Portland cement concrete including practices for materials selection, mixture proportioning, and construction of Portland cement concrete; mixing, casting, and testing of Portland cement concrete test specimens
Robotics and Embedded Research Laboratory
