Adding a small amount of lightweight course aggregate to a normal weight concrete mix to produce a clean, rough top surface so that manual or mechanical roughing of the top surface is not necessary. The lightweight course aggregate will float to the surface, and make a rough surface so that the bond and shear resistance of the interface (cold joint) between previously placed and newly placed concrete will be as strong as a manually roughened joint.

Method of forming a self-consolidating concrete construction with self-roughening properties

Provided herein is a cementitious composition comprising a photoactivator, wherein the photoactivator is capable of converting NOx to NO&#x2014; or NO&#x2014; when exposed to ultraviolet (U.V.) or visible light.

Corrosion inhibiting cementitious compositions

The present invention relates to a method for reinforcing mineral-based materials using reinforced fiber material. More particularly, the present invention relates a method for more uniformly dispensing a fiber material with a mineral-based material, such as cement paste.

Determinations are made related to the presence of a predetermined material in concrete under test using previously obtained model information. In one embodiment, the predetermined material includes a chloride material and the model information is obtained using a number of cured cement specimens. The model information is stored in memory, such as in the form of a look-up table. When the concrete is being inspected, one or more magnitudes of reflections coefficients are measured and such is utilized with the model information to make determinations related to the presence of the predetermined material. In developing the model information, each of the plurality of cured cement specimens is located in a bath containing the predetermined material. The bath may be pressurized. The cured cement specimens are maintained in the bath for different, known time intervals. After the known time interval for a particular specimen, it is dried and one or more magnitudes of reflection coefficients are measured. This data is utilized in preparing the model information.
