Elkin O. Influence of the shape of products on the structure and properties of concrete

The object of research - constructive concrete products and constructions, paving slabs, concretes and their structure; goal - improvement physical-mechanical properties of concrete due to controlling the distribution of technological local and integral deformations by changing the geometric shape of concrete products; methods - graphic-analytical method, photoelasticity method, nondestructive methods of determination of speed of passing of ultrasound with use of ultrasonic devices, standard techniques; results - methods of obtaining of technical deformations by change of coefficient of a form of the concrete bent element are offered, proposed forms the small-size paving products and coefficients of forms concrete and the ferroconcrete constructive bent elements with the improved physical-mechanical characteristics are offered, the recommendations to design of a geometrical form of paving slabs allowing to reduce gradients of residual deformations and to improve properties of material are developed; introduced - at production of small-size paving slabs.
