A study on the edm of al7075+3 wt%sic+3wt% b4c hybrid mmceSAT Journals
Abstract The objective of the project is to investigate the effect of current, pulse on time and pulse off time. For the proposed work Material removal rate (MRR) and Tool wear rate (TWR) were chosen as responses and Current, Pulse on time and pulse off time were chosen as process parameters. Hybrid Aluminium Silicon Carbide (Al 7075 + 3wt. % of SiCp+ 3wt. % of B4C) is used as work material and copper is used as tool material. Design of experiment technique is employed for the experimentation. The mathematical models are prepared by Response Surface Methodology (RSM) technique and Box Behnken Design (BBD) is selected to design the matrix for different combination of process parameters. After completion of the experiments analysis was done using analysis of variance (ANOVA) for 90% confidence level. Keywords: Current, Pulse on time, Pulse off time, Material removal rate (MRR), Tool wear rate (TWR), Design of experiments (DOE), Response surface methodology (RSM), Box-Behken design (BBD), Analysis of variance (ANOVA).
Evaluation of Compressive strength and Workability of normal concrete, Temper...IJERA Editor
The experiments conducted focuses on research to avoid shrinkage cranks and thermal expansion in concrete, the case study chosen for this experiment are underground structure having high rebar congestion. It became very critical while the mass or volume of concrete is more than natural. Generally the temperature controlled concrete for high mass or volume concrete. These type of structures are mainly foundations and under the ground only, where reinforcement area is very less and compared to concrete and concrete placing is also easy over there, but if the condition is not the same. When the situation is totally opposite of the assumption, the concrete to be done on height of more than 40 meter, and reinforcement volume is more and congestion is the condition can that concrete can’t reach the bottom. Here the situation for which this paper is written. We expectingthe same situation, so our aim is to check the compressive strength and yield strength of normal concrete, Temperature controlled (TC) concrete and Temperature controlled self-compacted (TCSC) concrete

2. INTRODUCTION OF SITE INVESTIGATION
Site Investigation is the geotechnical investigations
performed by geotechnical engineers or engineering
geologists to obtain information on the physical
properties of soil and rock around a site to design
earthworks and foundations for proposed structures
and for repair of distress to earthworks and
structures
3. PURPOSE OF SITE INVESTIGATION
1. Support planning and define the project feasibility.
2. Determine most economical and appropriate:
Route and depth definition.
Excavation and support methods definition.
3. Define physical characteristics of the soil, rock, and groundwater.
4. To minimize uncertainties of physical conditions for the bidder & to improve
safety.
5. Provide specific data needed to evaluate:
Constructability, Cost, Productivity, Schedule.
• To document as:
Built conditions of the completed project
4. INTRODUCTION OF PROBE MACKINTOSH
The site investigation is the one thing that must be done
before starting the construction of the building. This is
because the soil condition at the site need to
be identifies to determine the suitable foundation use for the
building and soil play a main role to support the load that come
from the building and the building
need a suitable foundation to transfer the load to the ground.
Therefore, the investigation of soil need to be
done to identify the type of soil to ensure the soil can
carry the load.
5. OBJECTIVE OF PROBE MACKINTOSH
• Collecting a disturbed soil sample for grain-size analysis and
soil classification
• Determine sub-surface straits graphed and identity materials
present
• Evaluate soil density and in-situ stress conditions
• Estimate geotechnical parameters

8. PROCEDURES
1. Equipment for the test is assembled. The cone diameter is measured in SI
unit.
2. Distance of 0.3 m is measured and marked on the rod start from the tip of
the cone
3. The equipment is set up on the ground
4. The hammer is pulled until it reached the maximum. The hammer is dropped
freely to driven the cone into the soils.
5. The sum of the number of blow for penetration of 0.3 m is recorded in the
data sheet.
6. The hammer is taken off on the last 0.3 of each rod and joined and existing
rod with another rod and lastly the hammer. The blow is continued and
stopped when :
The blow is more than 400 for 0.3 m penetration
The depth reached 15 m

18. CONCLUSION
JKR Probe Mackintosh is can be used to determine the thickness
of unsuitable material to be removed and also for preliminary
design of embankments, limited to about 15 m and must be
record no. of blows/ft. then correlates to established chart to
determine bearing capacity of soil. Mackintosh Probe which has
30° cone penetrometer while JKR Probes has 60° cone
penetrometer. This is a light dynamic test and the cone is driven
directly into the soil by driving a hammer 5 kg. Weight dropping
through a free height of 280mm. The probe is unable to
penetrate into medium strength soil and gravelly ground.
