Pozzolanic Activity Assessment of LUSI (LUmpur SIdoarjo) Mud in Semi High Volume Pozzolanic Mortar [PDF]
LUSI mud obtained from the mud volcano in Sidoarjo, Indonesia, is a viable aluminosilicate material to be utilized as pozzolanic material. LUSI is an abbreviation of the local name of the mud, i.e., Lumpur Sidoarjo, meaning Sidoarjo mud. This paper reports the results of an investigation to assess the pozzolanic activity of LUSI mud, especially in semi

ABSTRACT This study presents new evidence for the early use of lime mortar during the Early Iron Age at the Piscina Torta site (Ostia, Italy), situated on the earliest Holocene beach ridges in the southern Tiber delta. The site, which was earlier described as a briquetage site, dates from between the late 8th and 6th century BCE and consists of a large

Effects of the secondary minerals of the natural pozzolans on their pozzolanic activity
Abstract Natural pozzolans have been widely used as substitutes for Portland cement, because of their binding properties. Some of them are natural volcanic rocks which contain secondary minerals such as clays and zeolites corresponding to products of the alteration of the rock.

Our study provides evidence that active restoration of deep‐sea CWCs habitats is technically feasible when guided by a rigorous, multidisciplinary approach integrating habitat mapping, ecological aspects and long‐term monitoring. The methodological framework presented here is intended to provide an operational template for designing and scaling ...

Sugar cane bagasse ash as a pozzolanic material
This study aimed to verify the SCBA's potential use as a partial replacement of Portland cement. Therefore, the experiment was divided in two stages; in the first, mineralogical and chemical analyses were performed with two samples of ash, in-natura and ...

The influence of fly ash as substitute of cement in the durability of concrete [PDF]
Limitation of transport capacity through the concrete is one of the key points in the improvement of the material’s durability. The use of fly ash as an admixture to concrete is widely extended; a general consensus has been established due to the pore ...

ABSTRACT The use of laterite soil with high Al and Fe content has been investigated as a novel supplementary cementitious material (SCM) to replace traditional mineral materials for clinker substitution. High‐energy ball milling was used to mechanochemically activate laterite and change its reactivity.
