Objective - Provide the industry with measurement science tools to predict whether a concrete can be pumped, with SRMs (Standard Reference Materials) to calibrate concrete rheometers and with tools for quality control in the field.
What is the new technical idea? Fresh concrete is intended a
Objective: To achieve reductions in building heating and cooling loads and industrial energy use by decreasing measurement uncertainties of the thermal resistance of insulating materials through the assessment of room- and high-temperature insulating materials measurement methods (i.e., laboratory
Objective - Create new measurement technology and reference data that characterize the structure, composition, and reactivity of cementitious materials.
What is the new technical idea? The new technical idea is to create the measurement science, data and understanding required for the concrete
Objective - To develop the measurement science needed to enable greater industry use of innovative concretes, such as 3D printing, more durable and limestone replacement concretes.
What is the new technical idea? Manufacturing of cement and production/placement of concrete requires significant
