Strength of Humic Acid Aggregates: Effects of

2021-3-12  Aggregation–dispersion, charging, and aggregate strength of Leonardite humic acid (LHA) were investigated in CaCl2 and MgCl2 solutions as a function of pH and ionic strength (I). The strength or the withstanding force of aggregates of humic substances (HSs) against breakage is important because this force influences the transport and distribution of pollutants and nutrients along with HSs ...

High-Strength Structural Concrete with Recycled

The aim for this on - going project is to determine the strength characteristic of recycled aggregates for application in high strength structural concrete, which will give a better understanding on the properties of concrete with recycled aggregates, as an alternative material to coarse aggregate in structural concrete.

AGGREGATES AND POZZOLANIC MATERIALS OVERVIEW

2018-4-10  Aggregates are cost effective and stable fillers for concrete. Aggregates contribute to strength of hardened concrete and are stronger than the cement itself. Aggregates are volumetrically stable. Aggregates are typically locally sourced and as such are inexpensive. Cost is the driving factor in aggregate selection.

Tensile Strength of Porous Dust Aggregates -

Comets are thought to have information about the formation process of our solar system. Recently, detailed information about comet 67P/Churyumov-Gerasimenko was found by Rosetta. It is remarkable that its tensile strength was estimated. In this paper, we measure and formulate the tensile strength of porous dust aggregates using numerical simulations, motivated by a porous dust aggregation ...

The Effect of Aggregate Properties on Concrete

2000-3-30  Although aggregates are most commonly known to be inert filler in concrete, the different properties of aggregate have a large impact on the strength, durability, workability, and economy of concrete. These different properties of aggregate allow designers and contractors the most flexibility to meet their design and construction requirements.
