This technique is conventional for improving expansive soils properties [ 4 ]. Therefore two optimal compaction energies can be considered with respect to the variation of optimum moisture, the first when the optimal humidity reaches its smallest value and the second when it increases, after reaching its lowest value.

Bricks made of fly ashes, CaOH, and calcium sulfide are one of the best alternatives for bricks of conventional burned clay. The values stated in inch-pound units are approximate. This procedure is supposed to increase soil density.

The study of different materials for the fabrication of pieces to substitute bricks of burned clay has been the aim of many researchers worried about the environment, the use of natural resources, and the recycling of industrial trashes.

Plasticity limits versus percentages of CaOH are shown in Figure 1.

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

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.

Then, they were subjected to tests for determining the break modulus and the strength to first fissure [ 26 ] for comparison qstm commercial bricks.

In general, bricks frequently show different densities and therefore different resistances because the compaction energy is neglected in the production of this kind of bricks. By gradation analysis, via dry and humid, it was determined that the soil was a material with fines, since Auth with social network: So, the compaction energy aspect in this work is a new contribution in the production of bricks of better quality.

To make this website work, we log user data and share it with processors. 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. The compaction energy was selected to be the best reasonable strength.

If you wish to download it, please recommend it to your friends in any social system. Compaction properties and unconfined compressive strength at different ages. Results are displayed in Table 2.

Dial gage for measuring axial deformation. This is so because wood, recycled automobile oil, coke, heavy oil, used tires, garbage, and plastics [ 11 ] are used as fuels for its production. Application of Compaction Energies The compacting procedure for the stabilized soil was compaction by layers with a weight falling from a controlled height Proctor d266 procedure. Share buttons are a little bit lower.

Many countries in the world have to deal with the problem of expansive clays vertisols such as Mexico, the USA, Australia, South Africa, India, and Israel among others. We think you have liked this presentation.

This caused a poor compaction of the material low density values because water cannot move instantaneously under the compacting hammer blows [ 17 ].

ASTM D – 00 Standard Test Method for Unconfined Compressive Strength of Cohesive Soil

Therefore additional soil dispersions generate increase of water content. Balance, sensitive to 0. The compacting procedure for the stabilized soil was compaction by layers with a weight falling from a controlled height Proctor compaction procedure.

From the gradation via humid analysis, the percentage of particles less than 0. After applying these three energies, we observe that the best dried density of the material corresponded to the Proctor standard energy.

Abstract In general, bricks frequently show different densities and therefore different resistances because the compaction energy is not considered in their production. So, in this work the compaction energy aspect and the use of construction trash soils in the elaboration of resistant masonry bricks of homogeneous and controlled density are a new contribution in the production of bricks of better quality.
