With many years of construction and application of common concrete, researchers have always been searching for a better composition. One of the notable ideas for achieving such a composition is using recycled materials. One of the materials which is suitable for environment and constant development is damaged tires .For studying mechanical properties of concrete containing tire particles, a ser...

Disentangled ultrahigh molecular weight polyethylene dUHMWPE (Mw ∼ 2.106 Da) particles in a reactor blend with HDPE are catalytically prepared from ethylene, mediated by new catalyst N,N'-(2,6-pyridinediyl diethylidyne) bis[2,6-di-3-propenyl-benzenamine] iron dichloride and triethyl aluminum. These could be laser sintered, but not automatically processed an SLS machine. The same supported on mi...

Summary One-part geopolymers, known as “just add water” (JAW), alkali-activated formulation is presented in this work. This work reveals the design and development of short-term properties JAW geopolymers for use oilwell cementing well abandonment. Granite-based mix designs normalized with a byproduct slag small amount microsilica precursors were developed. The solid activator composed potassiu...

Sustainable construction requires high-strength cement materials that additives with silica content could provide the requirements as well. In this study, effect of micro and nano-size on compressive strength paste using different mathematical approaches is investigated. This study compares preferentially replaced pastes microsilica (MS) nanosilica (NS) incorporation by proposing several models...

Alkali–silica reactivity (ASR) is one of multiple reactions responsible for premature loss in concrete infrastructure service life. ASR results the formation expansive, white-colored gel-like material which internal stresses within hardened concrete. ASR-induced result cracking, spalling, and increased reinforcement steel corrosion rates. The main objective this research to improve conditions p...
