On March 1st, 2016, the CEE 3030 Construction Materials class mixed concrete with varying water cement ratios and created three, 3” diameter by 6” high cylinders and three, 6” diameter by 12” high cylinders. The cylinders were cast according to the ASTM C31 standard. The class was divided into sections, then the sections were divided into teams. The sections mirrored each other, and teams created concrete with 0.40, 0.44, 0.48, and 0.52 water cement ratio. Over the next 28 days the cylinders…

1. The concrete mix proportions for the batch were calculated before the beginning of the lab by a select few group members. Calculations were done with goal of the having the greatest early strength as reasonably possible. To accomplish this, the accelerator agent of calcium chloride was added at a proportion of 2 Ib. of calcium chloride to every 100 Ib. of cementitious material. This ended up being 0.483 Ib. of accelerator. The physical properties, like specific gravity and percent absorption,…

Reasons To Put Polished Concrete Floors In Your Shop If your shop needs new flooring, you might want to think about having polished concrete floors put it. They are durable and long-lasting, which makes them perfect for a store that gets a lot of foot traffic. Polished concrete has other benefits that makes it a good match for commercial use. Here's a look at some of them. Polished Concrete Reflects Light Polished concrete has a shiny surface that reflects light. This can brighten your shop…

Introduction As it would seam the development of concrete and arches played a massive role in the way Rome designed there structures. Particularly concrete changed the way they did things but it makes sense Rome learned how to literally make rock that would conform to almost any shape that they wanted. It was in many ways not just a massive achievement for Rome but it would effect us today with so much being made of concrete these days. Concrete While concrete may not seem like the most…

improvement in architecture, monuments, entertainment, and literature. The aqueduct and concrete are among the best architectural advancements made by Rome. The arched structure that we know as aqueducts use gravity to transport water through pipelines and into city centers. The aqueducts promoted sanitation and allowed Romans to enjoy many luxuries like toilets, sewage systems, fountains, and baths. Concrete is also a useful architectural development of Rome and it was used to make stronger…

has over concrete, such as being extremely resistant to cracking. Listed below are just two of the many reasons to pave your driveway with asphalt. It Does Not Crack As Easily As Concrete The primary reason to pave your driveway with asphalt is that it does not crack as easily as concrete under most conditions. This is because asphalt is designed in a way that allows it to be a bit more flexible, which means that it will flex when it experiences stress rather than cracking like concrete does.…

A concrete patio or entryway is a standard on most homes in Texas. Owners don’t typically even acknowledge that they can transform this feature of their home although it’s typically the first thing a visitor sees. A concrete overlay is a cost efficient way to add style and a modern touch to the front of a home to boost its curb appeal.

These are the steps involved if you want to do the job yourself. Clean The Concrete First The first step is to clean your…

glorified buildings. They wouldn’t be able to indulge, though, their architectural ambitions having not invented the concrete. Both concrete and the arch had a lasting impact on architecture throughout the world. This essay will examine the development of the concrete and arch, their importance of each in the life of Rome, as well as their results. The development of concrete Roman concrete is an artificial material composed of an aggregate, a binding agent, and water. Aggregate is a filler,…

Geopolymer Concrete Mixtures: In the mix design of geopolymer concrete the role and the influence of aggregates are considered to be the same as in the case of Portland cement concrete. The mass of combined aggregates may be taken to be between 75% and 80% of the mass of geopolymer concrete. Coarse and fine aggregate together were taken as 77% of entire mixture by mass. Fine aggregate was taken 30% of total aggregate. Fly ash and alkaline liquids was taken 23% of density of concrete. From past…
