OBTAINING BINDER COMPOSITIONS OF OPTIMAL COMPOSITIONS BASED ON PORTLAND CEMENT AND CERAMIC BRICK WASTE

نویسندگان

چکیده

When developing composite binders of a certain functional purpose, it is necessary to rationally select raw materials, taking into account their chemical, mineral and granulometric composition. The use mechanical activation with the choice most suitable grinding unit affects creation binder compositions, additives used have significant impact on properties binders.
 article presents results obtaining compositions optimal composition based Portland cement broken ceramic bricks. Experimental studies been carried out, tests compositions: – bricks prepared in mill are given. Compositions wide range cullet waste brick production developed installed.
 Using method electron microscopy, features microstructure chips stones synthesized basis various content filler slaughter waste, mechanically activated vibration mill, were studied. It noted that open pores stone chips, binders, densely overgrown neoplasms sizes.
 has established hydrated marked by dense structure due powdered cullet, which compact composite, also grains calcium hydrosilicates grow particles filler, compacting overall composite.

Compositions versus Cyclic Compositions

We prove that the sum of greatest common divisors of parts in all compositions of n equals the sum of lengths of all cyclic compositions of n. The proof highlights structural similarities between the set of compositions of n and the set of cyclic compositions of n. 1. Definitions and Statement A composition of the positive integer n is an ordered partition of n; that is, a vector ( ) r p p ...,...

Reversible Logic Synthesis by Iterative Compositions Portland Quantum Logic Group

A reversible circuit maps each output vector into a unique input vector, and vice versa. CMOS reversible / adiabatic circuits are currently the most important approaches to power optimization. This paper introduces an approach to synthesize generalized multi-rail reversible cascades for singleoutput Boolean functions. Minimizing the “garbage bits” is the main challenge of reversible logic synth...

Continually Learning Optimal Web Service Compositions∗

Open service-oriented systems which autonomously and continually satisfy users’ service requests to optimal levels are an appropriate response to the need for increased automation of information systems. Given a service request, an open service-oriented system interprets the functional and nonfunctional requirements laid out in the request and identifies the optimal WS composition— that is, ide...

Fuzzy Relational Compositions Based on Generalized Quantifiers

Fuzzy relational compositions have been extensively studied by many authors. Especially, we would like to highlight initial studies of the fuzzy relational compositions motivated by their applications to medical diagnosis by Willis Bandler and Ladislav Kohout. We revisit these types of compositions and introduce new definitions that directly employ generalized quantifiers. The motivation for th...
