ACI Certification - Concrete Concrete Work Element Credit for ACI Certification. You'll have a head start in meeting NICET's examination requirement for the Construction Materials Testing subfield of Concrete if you have one or more of the following ACI certifications:
Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens over time—most frequently a lime-based cement binder, such as Portland cement, but sometimes with other hydraulic cements, such as a calcium aluminate cement.
Introduced by ACI in 2007, the Aggregate Testing Technician (ATT) – Level I Certification was developed to certify laboratory technicians in the sampling and testing of concrete aggregates. Certification assures owners, specifiers and other interested parties that the testing of aggregate is conducted by the qualified laboratory personnel.

Aggregates influence the properties of concrete/mortar such as water requirement, cohesiveness and workability of the concrete in plastic stage, while they influence strength, density, durability, permeability, surface finish and colour in hardened stage. Field Tests for Aggregate 1.
Concrete and aggregate used in your construction projects has to meet strict regulations and quality standards. As these standards are often compulsory, concrete and aggregate testing by an independent third-party is necessary to help assure compliance.
Cement Standards and Concrete Standards ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.
For aggregate testing, Humboldt provides a large selection of sieves including ASTM testing sieves in a variety of sizes and mesh configuration. These sieves can be used in all types of sieve testing applications, from sampling and classification of soils, aggregates and other powdered and granular materials to specific ASTM standard tests.

Various Lab Test On Aggregates ... Aggregates are very important component of concrete, so the quality really matters when it comes to aggregates. Various test which are done on aggregates are listed below. 1. Sieve Analysis 2. Water Absorption . Advertisements. 3.
The measurement is from the bubbles in the concrete compressing under the increase in pressure. The only ingredient in the concrete that is compressible is the air. Cementitious material, water, and aggregates do not respond to the small rise in pressure. So the pressure change is correlated to the air content of the concrete.
