Concrete. Focus areas are testing, acceptance and approval of products such as admixtures, curing compounds, prepackaged concrete products, freezethaw durable aggregates, and other miscellaneous products related to concrete. Other focus areas include research studies regarding concrete applications, and methods of improving concrete quality ...
Soil. Monitoring the soil compaction on site, in the field or in a lab, Proctor compaction testing or moisture content determination these are just a few of the standard test methods aimed at ensuring formation of a stable pavement carrier in road construction, a solid base for canalization, or high loadcarrying base for foundations in highrise construction.
HYDRAULIC STRUCTURES, EQUIPMENT AND WATER DATA ACQUISITION SYSTEMS – Vol. IV Testing of Materials and Soils F. Druyts ©Encyclopedia of Life Support Systems (EOLSS) The Proctor Compaction Test is a laboratory procedure designed to bring soils to approximately the same state of density that is obtained when earth dams are compacted
The inspection methodology consisted of field inspection, concrete core extraction (material sampling), laboratory testing and analysis followed by engineering evaluation. Fourteen concrete core samples were extracted from the dam's wing walls and pier walls for laboratory testing including Chloride Ion Sampling, Petrographic Analysis, and

A core is usually cut by means of a rotary cutting tool with diamond bits. The concrete core drilling machine is portable, but it is heavy and must be firmly supported and braced against the concrete to prevent relative movement which will result in a distorted or broken core, and a water supply is also necessary to lubricate the cutter.

of real building structures. It does not deal with testing cores made at the laboratory, but taken from real elements made of the stressed concrete. The extraction of testing cores has been taken in real structures elements and it has been proceeded to use a uniaxial compression test in order to obtain the real resistance of the concrete in the ...

METHOD OF TEST FOR LENGTH OF DRILLED CONCRETE CORES A. SCOPE This method describes the procedure for determining the length of a core drilled from a concrete structure, particularly from a concrete pavement. This method is a modification of ASTM C .
After core extraction, the core hole shall be completely filled with water, to measure permeability of interior concrete for a duration of 8 hours. The contractor is responsible for filling each core hole with a nonshrink grout, and restoring all surface areas damaged by contractor's operations.
Core drilling is a necessary step at some point for virtually all concrete structures – Whether you need to make an opening for a manhole, install plumbing or electrical lines, or to pull a sample of concrete for testing, quality cores are a must.
Soil core sampling equipment is used to collect virtually undisturbed soil core samples for soil profiling and environmental investigations. AMS offers soil core samplers, split soil core samplers, and multistage soil core samplers. All of these quality soil core sampling tools allow the user to collect soil core samples into removable liners.
RESULTS OF PETROGRAPHIC EXAMINATIONS AND LABORATORY TESTING OF CONCRETE CORES INTRODUCTION BACKGROUND Nine, 33/4" diameter concrete cores from the referenced project were obtained by Terracon, Tampa, Florida personnel and were received at the Terracon Cincinnati, Ohio materials laboratory on July 3, 2013.
