Asbestos Tailings

Preliminary studies having shown that it is possible to use the solid part of various asbestos tailings as concrete aggregates, a complete study of two tailings considered particularly suitable for this purpose was undertaken. The dust was first removed from the tailings, and these were submitted to the usual tests (absorption, sulfate soundness, etc.). The tailings were then used to make concretes that were later compared to concretes made with normal aggregates from the Quebec City area. These tests showed that the tailings could be used as aggregates, but that the quantity of cement paste required to obtain a given slump was much higher than that of normal mixes. The making of concrete with asbestos tailings as aggregates was thus found to be uneconomical. The concrete s made with the tailings were also found to be much more deform able than normal concretes.

Herpesvirus 6

Seroprevalence of antibodies against human herpesvirus 6 was determined in a sample of 303 randomly selected individuals from the Quebec City area. The influence of different variables on antibody litres was also evaluated. Human herpesvirus 6 was grown in the HSB-2 cell line, and antibody litres were measured by indirect immunofluorescence. Serum samples were collected from 177 females and 126 males ranging in age from two months to 88 years. Ninety-nine per cent (300 of 303) of this population had an antibody titre of at least 1:10, whereas 75% had a titre of at least 1:80. Women had a higher geometric mean litre than men (P=0.06). This difference between sexes varied according to age and became statistically significant in subjects older than 20 years of age (P=0.04). It was found that this difference was attributable to higher antibody litres in women in the 15 to 40 year age group who had previously had children.
