With the help of dilatometry analysis theoretical assumptions of influence of grain shape and size on dilatation value of sands were confirmed. Determined was the possibility of dilatometry analysis employment for preparing special (hybrid) sands with lower and/or more linear character of dilatation. %K Innovative Foundry Technologies and Materials %K Product Development %K Silica Sands %K Hybrid Sands %K Dilatometry and Chemical Analysis %U http://versita.metapress.com/content/6535v7513565j075/?p=bfc61d9c313f42d3a47da514242072e3&pi=1
