Stabilized-soils tests specimens were prepared and subjected to unconfined compression, following the ASTM D standard [ 25 ]. To use this website, you must agree to our Privacy Policyincluding cookie policy.

The compaction energy was 2d166 to be the best reasonable strength.

Unconfined Compression Test ASTM D /02 – ppt video online download

Indeed, at that percentage there is little or nil variation of the liquid limit and the plastic index, even increasing the CaOH content. We think you have liked this presentation. After applying these three energies, we observe that the best dried density of the material corresponded to the Proctor standard energy. Higher compaction energy values do not improve density. So, the compaction energy aspect in this work is a new contribution in the production of bricks of better quality. Test specimens of modified soils were subjected to unconfined compression [ 25 ] at different ages 7, 14, 30, and 60 days and the compaction energies mentioned above.

This process is obtained with suitable techniques applied on the soil, which improves the dry specific weight decreasing its empty spaces. S — Soil Mechanic.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Application of Compaction Energies The asgm procedure for the stabilized soil was compaction by layers with a weight falling from a controlled height Proctor compaction procedure.

Due to this problem, these soils are replaced d21666 soils with inert features [ 2 ], thus remaining as trash soils. It should be pointed out that the modified soils tests specimens had the optimal amount of CaOH, previously determined. The compacting procedure for the stabilized soil was compaction by layers with a weight falling from a controlled height Proctor compaction procedure.

Expansive soils represent a problem for light buildings over them because of volumetric instability. From the gradation via humid analysis, the percentage of particles less than 0. Advances in Materials Science and Engineering. Subscribe to 00 of Contents Alerts.

The objective of this study is to use this trash expansive soil via a composite material, soil-CaOH, to produce bricks of optimal and controlled compaction energy for masonry, which is neglected in the production of this kind of bricks. Achenza and Fenu [ 16 ] reported bricks with adobe stabilized with vegetal fibers and a composite of natural polymers. Carrasco Urrutia, and L. From Table 2it can be observed that the best results for the proposed brick under study 000 obtained at 60 days.

My presentations Profile Feedback Log out. Moreover, the soil classification changes from CH high compressibility clay to ML lime of low plasticity ; thus, it has properties of a low plasticity soil, that is, little or nil volumetric change.

Unconfined Compression Test ASTM D-2166 /02

The volumetric shrinkage limit was 8. The specific energy of soil compaction is the compaction effort applied to the soil per unit volume and is determined using the weight, height of drop, and number of blows of a hammer to compact a volume of soil placed in layers into a mold.

Indeed, it has been used widely in walls construction around the world, especially in developing countries [ 6 ]. Remolding device if remolded sample is tested.

This is a cut material extracted from sedimentary rocks as shale. This procedure is supposed to increase soil density. Results are plotted in Figure 2.

Mohr Circle for stress In 2D space e. If you wish to download it, please recommend it to your friends in any social system. The authors declare that there is no conflict of interests regarding the publication of this paper.

Soil compaction produces an increase in resistance and decreased deformability.

Note The determination d166 the unconsolidated, undrained strength of cohesive soils with lateral confinement is covered by Test Method D The aim was to find the optimal CaOH quantity for abating volumetric changes. View at Google Scholar D. The liquid limit was Several test specimens of soil added with CaOH with different percentages in dry weight were prepared.

Indexed in Science Citation Index Expanded. Then, following the ASTM standard [ 19 ], the liquid and plastic limits were determined, as well as the shrinkage limit [ 20 ].

Since fifty years ago, the introduction of blocks made of compressed earth was seen as an important step.
