    Abstract. The general concentration dependence of nano-modification of materials (polymers, ceramics, cement) with carbon nano-tubes and nano-silica is considered. Experimental results of low-water demand cements LWDC-100 and LWDC-50 modification by adding different types of nano-sized silica additives introduced during the production process of this composite cement binder are presented. It is determined that all nano-silicas significantly increase the strength of hardened LWDC-100, and the most valuable effect is achieved with a modifier "Kovelos 35/01 T". On the basis of this work, it is established that nano-modification of low water demand cements is one of the methods for improving the cement binder, economic efficiency of which is due to the extremely low content of a nano-additive, at this its cost is not significant.
    Key words: nano-modification, general regularity, nano-silica, low water demand cements, strength.
