rephrase the following:
In order to achieve maximum compressive strength, one must pay very close attention to tools and procedure when acquiring materials and preparing mix. The design is set for a specific amount of materials and lab and equipment conditions will affect the results if not cleaned properly, measured properly, and lack of knowledge of handling of equipment. When preparing mortar specimen it is possible we added too much or too little water to multiple specimens.
Something our group did specifically is when our material was running low we did not have enough to fill one final cube. Instead of redoing the procedure we added additional, freshly mixed mortar, on top of the old mortar. This lead to an obvious division of levels which caused high stresses along the point of separation. This action could fracture.
Weighing device used was inconsistent in its measurements, therefore, we did not always have the proper weighted amount of materials.
These results are unsettlings. Due to the human and trial error we did not achieve best desirable results. Our compressive strength should’ve gradually increased throughout its curing process. However, we do see a positive linear trend, but, the 28 day strength should’ve been more than the 7 and 14 day strength.
The biggest issue we had with our results probably came from our preparation. The procedures were followed accordingly but without the highest degree of accuracy.
For instance, on the packaging, it tells you to weigh out a specific amount of material before preparing your specimens. This insures maximum strength compatibility. By not following the design to 100% accuracy our results were punished.
Another big issue is the addition of water. Water improves the strength of our mix but if it is in balance with our other materials. Adding to much or too little water can drastically change your results. By adding to much we make the compound to fragile and watery. Therefore the curing process takes longer and the material is susceptible to fractures and brittleness.
Although these results show consistency with what we would have expected from this experiment it is quite obvious something went wrong with our 28 day test. Human error lowered our compressive strength we should’ve had our maximum instead we got something much lower.
Solution
How to overcome small issues that has a significant effect in a larger scale:
Aim:
Our main objective is to achieve the Maximum compressive strength of mortar bricks.
Experiment:
First all the materials were collected, batched according to weights and volumes, prepared Cube samples, cured and tested for 7,14,28 days strength.
The 7, 14 days results showed positive linear trend but the 28 day strength has deviated, much lesser value than the former ones.
Later we realised that various circumstantial, unforeseen practical issues and human errors during the experiment made it hardly possible for us to achieve the objective.
Here we listed a few of them:
Inference:
Following the guidelines for the sake of following, end up with comprimising results, hence the best way is to give our best in each step until we get what we desired.
