Abstract
Quality variations of concrete containing cellulose ether in full-size models of structures relative to the depth and width were examined by strength, absorption and density of cores drilled from the models and pulse velocity and rebound number of each part of the models comparing with conventional concretes. Quality variations of concrete containing cellulose ether in the model structure were smaller than those of conventional concretes. It may be caused by the effect of cellulose ether on controlling segregation of concrete.
Otherwise strengths of construction joints in concrete specimens were examined by splitting tests relating addition of cellulose ether. Strengths of construction joints were increased when the old concrete was containing cellulose ether. It may be caused by little laitance because of controlling bleeding.
As the results of the experimental investigations it may be stated that the addition of cellulose ether improves heterogeneity characteristics of concrete in structures.
