The purpose of this research is to study the effect methods preliminary preparation thermally activated clay, which a pozzolanic component in water-resistant composite gypsum binders, as well mechanochemical activation joint grinding clay with addition plasticizer on activity and change required number composition binders. It was found that amount gypsum-cement-pozzolan when ground specific sur...

The article presents modern research on the development of compositions and technologies light aggregates based natural man-made raw materials, as well mixtures containing both materials. As a material component, shungite, clays, silica – materials-diatomite, trepel flask are used. coal-enrichment waste coal-containing waste, fly ash, ash slags, oil sludge paper Light aggregate is prepared acco...

The use of cementitious products isincreasing in the world,Thusreplacement part of cement with pozzolanic materials reduced energy consumption and preserve natural resources and the environment and also improve the mechanical properties and durability of the cement mortar.Furthermore Nano technology has promptedto tremendous developments in technology of building materials in recent yearsso use...

The effects of calcination on spent bleaching earth ash (SBEA) were investigated in terms its contribution to pozzolanic reactivity as well the strength blended cement mortar when used partial substitution. SBEA waste, which is plentiful global stock, showed some potential material reduce reliance traditional clinker cement. However, actual research use replacement and how it may benefit from w...

Banyaknya penggunaan beton dalam bidang konstruksi membuat upaya penciptaan mutu yang baik dan ekonomis. Salah satu tersebut dengan memanfaatkan abu terbang (fly ash) sebagai pengganti sebagian semen pada beton. Berdasarkan itu dilakukan penelitian tentang Pengaruh Penambahan Abu Terbang Sebagai Subtitusi Semen Terhadap Kuat Tekan Beton Mutu Normal 30 MPa. Metode digunakan ini adalah metode eks...

In this paper, we discuss the presence of volcanic pozzolans in structural mortars Roman Temple Nora Sardinia (3rd c. AD), represented by pyroclastic rocks (pumices and tuffs) employed as coarse fine aggregates. The provenance these materials from Phlegraean Fields was highlighted through a multi-analytical approach, involving Polarized Light Microscopy on thin sections (PLM), Scanning Electron...
