Pavement Concrete

In this paper, a new method is proposed to measure the early shrinkage of airport pavement concrete material. Also, the effect of fly ash with different grades and dosage on early shrinkage and late shrinkage deformation of commercial concrete were studied. The effect of fly ash with different grades and dosage on volume stability of commercial concrete was assessed by using the test method of shrinkage cracking, and the causes and mechanism of the effect were analyzed.

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.
