PREDICTION AND OPTIMIZATION OF THE FRESH AND HARDENED PROPERTIES OF CONCRETE CONTAINING RICE HUSK ASH AND GLASS FIBER USING RESPONSE SURFACE METHODOLOGY

Substantial efforts are being adopted worldwide for the proper utilization of waste materials and by-products as supplementary materials to produce sustainable concrete.Rice Husk Ash (RHA) and Glass Fiber (GF) are such materials that can contribute to improve the properties of cement concrete.This study aims at predicting and optimizing the fresh a

Confirmatory factor analysis is some of the most widely used statistical techniques in the social sciences.Frequently, variables (i.e., items) stemming from questionnaires are analyzed.Two competing approaches for estimating confirmatory factor analysis can be distinguished.First, ordinal variables could be treated as in the case of continuous vari

As part of the celebration of the International Year of Chemistry - 2011, the 70th anniversary of the first adamantane synthesis was marked in Zagreb.This article collegiate graduate saddle addresses the retrospect of the synthesis of adamantane by Prelog, as well as presents a review of the research in adamantane chemistry in Zagreb from 1971 to t

Liquefied natural gas (LNG) is a viable, environmental-friendly alternative marine fuel.Several LNG-fueled vessels are already operating, and the LNG market is expected to grow further in the next years.A capillary marine LNG infrastructure network is developing to strengthen the fuel supply chain, which includes small-scale LNG storage and bunkeri
