Roman Numerals advancing the knowledge of mathematics‚ more organized cities through grid plans‚ and strong roman structures from roman concrete‚ are three artifacts that are some of the most historically significant developments in the civilization of ancient Rome. Roman Numerals‚ symbols that represent numbers‚ originated around 8th century B.C. to 2nd Century AD‚ to help record numbers in coins‚ art and stones. They are one of the most significantly important artifacts not only for Rome but the

fine particles of wood (Wikipedia‚ 2012). This will be used as admixture in the study. Rice Straw Ash is rich in silica‚ and a by-product of burning of rice straw. Silica is known to be very effective in enhancing the strength and durability of concrete. Clays are distinguished from other fine-grained soils by differences in size and mineralogy. Clay is one of the oldest building materials on Earth‚ among other ancient‚ naturally-occurring geologic materials such as stone and organic materials

aggregate particles improve the workability of fresh concrete during mixing so they are good for preparing portland cement concrete. * Angular and rough particles are good for asphalt concrete and base courses because they increase increase the stability of the materials in the field and reduce rutting. * Flaky and elongated aggregates are difficult to compact during construction and are easy to break so they are should not be used for asphal concrete. * Soundness and Durability: * Soundness

significant tendency for large and fine particles in a concrete mix‚ separate among each others. Segregation is caused by * Too wet mix‚ extremely high workability or less cohesive mixture causes the mixture unable to hold heavy aggregate * Dropping from excessive height * Over compaction of fresh concrete. Two methods to minimize segregation in fresh concrete: * Adequate workability is enough. * Don’t over compact the fresh concrete. (b) * If over or extremely high workability

was built and well maintained over centuries of abuse. What made this durability and endurance was the invention of concrete. “Roman building techniques reveal a combination of practicality and innovation: The Romans were the first to use concrete (an aggregate of sand‚ lime‚ brick-and-stone rubble‚ and water)‚ a medium that made possible cheap large scale construction‚ (74)”. Concretes combination of durability and economics made building a structure of that size (holding up
