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.

The disposal and waste management of solid high energy propellant (HEP) is a considerate conservational problem. HEP currently disposed in open or confined burning which may cause environmental hazards. In this paper, we examined discussed results on recycling into fired clay bricks baked different orientation. modified with 1.5%, 3% 5 wt. % content were manufactured tested, then compared again...

This study investigates the feasibility of recycling various waste paving blocks as raw materials for concrete. The rate in Korea remains around 11%. Therefore, three types blocks, i.e., recycled clay-, granite-, and concrete block, were used partial replacements sand a mixture at 10%, 20%, 30% replacement ratios. According to Korean standards pavers building bricks, compressive strength, flexu...

In recent years, the management of construction and demolition residues (CDRs) has become a major challenge for industry due to increasing volume waste produced its associated environmental impact. The aim this article is assess effect fine-grained fractions (<0.125 mm–0.6–0.125 mm) residues, obtained by industrial sorting in CDR processing plant Rovigo (Italy), on technological behavior tec...

The aim of this study was to produce bricks using boron waste Eskişehir Kırka region and fly ash Seyitömer thermal power plant. At the end study, it aimed that are more durable than normal bricks, resistant freeze-thaw having insulation properties in terms physical mechanical. 10% kept constant 10%, 20% 30% were used produced within scope study. carried out three phases. In first phase, 100% cl...

Electronic commerce has taken off. Whatever concerns about consumer acceptance there were five years ago have given way to “click and mortar” business models where ecommerce has an established role complementing traditional commerce. The digital publishing market segment, approximately $8 billion today, is expected to reach $70 billion by 2004. A significant portion of the GDPs of the industria...

We address a question posed by T. Sibley and Stan Wagon. They proved that rhombic Penrose tilings in the plane can be 3-colored, but a key lemma of their proof fails in the natural 3D generalization. In that generalization, an object is built from bricks, each of which is a parellelopiped, and they are glued face-toface. The question is: How many colors are needed to color the bricks of any suc...

This paper presents the results of experimental and analytical studies mechanical thermal properties laterite composites mixed with reprocessed low-density polyethylene waste (LDPE), calcium phosphate (CaP) phosphogypsum wastes, biochar to form brick composites. Bricks mixtures 20% by volume LDPE, 15% CaP, gypsum were shown have excellent compressive strength, flexural fracture toughness. The 1...

The present study was undertaken to improve the quality and increase the life time of magnesia-chromite refractory bricks used in the copper and lead industries. The results show that a decrease in the amount of large chromite particles in the formulation improves the thermomechanical properties and also reduces the slag penetration in the bricks. In addition it was also observed that the use o...
