cement is a binding material used with fine aggregate to produce mortar for masonry, or with sand and aggregates to produce concrete. construction cements are usually comprised of lime or calcium silicate and combined with fly ash. they are categorised as either hydraulic (e.g. portland cement) or non-hydraulic, depending on their ability to set in water.

pachometer testing - pachometer testing is used to locate existing reinforcing steel in concrete structures. this equipment can determine the concrete cover, rebar sizes, spacing, and length. windsor probe testing - windsor probe (astm c 803) testing methods can be used for assessing the general quality, uniformity, and relative strength of concrete members.

Testing cement for quality and reliability

Testing Cement For Quality And Reliability

soundness of cement can be determined by a variety of methods. in the le chatelier water bath method, a specimen of hardened cement/fly ash paste is placed in a mould and boiled for a fixed amount of time (approximately 3hr) so that any tendency to expand is speeded up and can be detected.

Compressive Strength of Concrete -Cube Test, Procedure

Compressive Strength Of Concrete -Cube Test, Procedure

sampling of cubes for test. clean the mounds and apply oil. fill the concrete in the molds in layers approximately 5 cm thick. compact each layer with not less than 35 strokes per layer using a tamping rod (steel bar 16mm diameter and 60cm long, bullet-pointed at lower end).



three steel molds were used to cast mixtures. the first mold was with dimensions (50×50×50) mm to test compressive strength, bulk density and absorption test. the quantities of materials used for mixing is as in table (6). the second mold was with dimensions (160×40×40) mm to test the flexural strength.

several variables contribute to define the quality of the concrete utilized for a structure: workability, consistency, setting time and air content are only few examples. matest proposes a wide range of testing equipment and high stiffness compression machines (manual, semi automatic or automatic) which allow to test concrete cubes, cylinders and blocks and satisfy the en and other international standards.

Procedure for Concrete Sample Preparation | Concrete

Procedure For Concrete Sample Preparation | Concrete

concrete is placed in the molds using a trowel in three layers of approximately equal depth and is remixed in the mixing pan with a shovel to prevent segregation during the molding of specimens. the trowel is moved around the top edge of the mold as the concrete is discharged in order to ensure a symmetrical distribution of the concrete and to minimize segregation of coarse aggregate within the
