Determination and Application of Microscopic Index Rca in Evaluating the Mechanical Properties of Soils

IOP Conference Series: Earth and Environmental Science, 2021
Abstract This paper presents an elaborated discussion on a soil microstructural index: the contact area ratio R ca, including its determination method and potential applications. Starting from the calculation of 3D porosity, a reliable threshold is obtained by introducing the connection between macro and micro ...

Inserting Keys into the Robust Content-and-Structure (RCAS) Index

2021
Semi-structured data is prevalent and typically stored in formats like XML and JSON. The most common type of queries on such data are Content-and-Structure (CAS) queries, and a number of CAS indexes have been developed to speed up these queries. The state-of-the-art is the RCAS index, which properly interleaves content and structure, but does not ...

Towards sustainable construction: RCA under different crushing techniques to determine the utilisation potential index for concrete production

Sustainable Materials and Technologies
The construction industry is associated with the largest contribution to global greenhouse gas emissions so as the largest consumption of natural resources and production of waste. Concrete consists of 70 % to 80 % of aggregates and that makes it also easily recyclable into reusable granular material, so-called recycled concrete aggregates (RCA), for ...
