Cement and concrete research paper submission

The 2 GHz GPR antenna with two polarizations transversal and longitudinal was able Cement and concrete research paper submission identify both types of scanned targets shallow and deep in just one scan.

For a research study, it is not easy to achieve different degrees i. Please allow 2 months for PCA to review a draft of the report prior to publishing. The processes start with concrete slab fabrication followed by the results of imposed current technique and data collection by scanning a reinforced concrete slab using 2 GHz of the GPR.

Apply the simapro software to create a LCA of the various Charcrete formulations. Corrosion has been recognized as a major deterioration phenomenon which leads to the structural concrete degradation due to environmental actions [ 2 ].

The result was expressed as the relative capillary absorption index as proposedby [31]. The strength of specimens at other ages has similar trends and the 0. Stock culture of B. For more information, see the "Project Changes" section. Sieve Analysis Test Particle Size Distribution or sierve analysis test were carried out on the fine sand and coarse granite aggregates in accordance with 34 2.

Data Availability The authors state that all the data used in this study are included within the manuscript. The intensity was measured in counts per second cps. The process was continued until the different rebars were corroded to the required degree by varying the exposure times.

The advantages of using this technique are that a high degree of corrosion can be obtained within a short period of time and the easy control of the desired degree of corrosion.

This study simulates the concrete under the effect of fire to research the effect of nano-clay on the compressive strength and heat transfer coefficient of concrete. All data are mean values of test results in triplicate.

This is leading in a somewhat different research direction than originally proposed. Several results can be obtained by using the GPR technique for assessing rebar corrosion in a concrete slab. Fine Aggregate Fine aggregate used was obtained from clean river sand at Oyigbo, a suburb of Port Harcourt.

Furthermore, the actual degree of corrosion or level of mass loss for the corroded steel specimens could be measured as the difference in mass of the bars before and after testing through equation [ 51 ]: Also, the slide held a special film on its external surface removing minimum friction during the drag of the antenna on the PSG, as shown in Figure 7 b.

Compressive Strength of the cement mortar and concrete was determined at 7, 14 and 28 days. The corrosion products of rebar c have diffused to a shallower cover depth, as shown in Figure 16 a. Its properties after being subjected to heat are affected mainly by the change of water content as well as the decomposition and fusion of minerals.

Secondly, the corrosion levels of the rebars were based on the percentage of the difference between weight of initial and final mass using 2 [ 52 ]. After obtaining the images from GPR, GRED software was used to obtain data images which were subsequently processed using image processing techniques.

ProfessorName, title, department, and a brief description of area of expertise and background. Nano materials have special characteristics, including the surface effect, small-size effect, quantum size effect, macroscopic quantum tunneling effect, and others [1] [2].

Based on the capability of the GPR method to investigate corrosion, this paper proposes an assessment of rebar corrosion using GPR on a concrete slab with embedded corroded steel bars.

The split tensile strength of the cylindrical cubes was determined at 7, 14 and 28 days, in accordance with 39 2. Therefore, the compressive strength of concrete can be calculated by ignition loss, or the ambient temperature of concrete can be calculated by ignition loss Figure 5.

The duration of current applied for each rebar. This condition may have happened due to the cracked concrete cover which affects rebar c. Cantor [ 16 ] developed the basis of analysis and interpretation techniques in these areas.

This indicates that the polymer addition results in reduction of the porosity of the pastes. For solid medium, a final concentration of 1. Bang, Microbiologically induced sealant for concrete crack remediation, 16th Engineering Mechanics Conference, 16—18 JulySeattle, Washington.

Thereby, by applying the mentioned method to make the said particular composite systems, "considerably increasing the modulus of resilience and the bearing capacity in bending" together with "the significant decrease of the weight" and "the removal of the beam fracture possibility of primary compressive type" have been feasible.

Quantification of a-scan derived from Figure 8. There are no significant differences in the waves peak i. Type deformed steel reinforcement is selected for the rebars having a diameter of 20 mm.

Abstract Corrosion of steel reinforcement is a major cause of structural damage that requires repair or replacement.submission is for the main Cement and Concrete Science conference, or for the Workshop on Waste Cementation – or if you would like to prepare a poster for presentation at both events, that is.
