Performance measures are used to observe progress and to measure actual results compared to expected results. They are usually expressed in quantifiable terms and should be objective and measurable (numeric values,

Comparative Study of the Abrasion Resistance

A series of concrete mixes were prepared and tested in the laboratory installations at Purdue University Calumet to determine which mix would show higher resistance to abrasion. Tests were performed during summer and fall of 2007 on 16 mixes with two finishing conditions. This investigation included preliminary testing on three different mixes.

Concrete pumping prediction considering different

Highlights. The effects of different rheological measurements on predicting the concrete pumping were examined. The plastic viscosity of the lubrication layer plays a governing role in determining the pumping performance. The values of lubrication layer thickness should be altered depending on the rheological properties of lubrication layer.

Prediction of moisture curling of concrete slab | SpringerLink

Sep 21, 2010 · Moisture curling occurs due to non-uniform moisture distribution in a concrete slab. The curled geometry and self-weight of the slab induce undesirable high stress region near the drying surface, and may cause cracks when external wheel loadings are applied. Therefore, alleviating the degree of curling is an important issue in pavement design, and a proper prediction scheme is essential in
