2.ashlar masonry consists with extremely fine bed and end joints.
3.Stones may be either square and rectangular shaped.
the answer is rupture
Laborers built a wide bank of rubble around the base of the pyramid to serve as a foundation. This bank was then faced with fine Tura limestone.
Common building materials of the Aztecs were wood such as pine and oak, plaster, adobes, lime, obsidian as well as rubble and loose stones. The Mexicans used materials as well as cement rock, wood, plaster, paint, they did not use rubble, they used the same material to make their temples bigger, European people do not understand the cosmology of the ancient Mexicans
The Native American mound builders constructed impressive earthen mounds for various purposes, such as ceremonial or burial sites. The mound builders lived in the Midwest and Southeast regions of the United States. Archaeologists study the remnants of these mounds to learn more about the ancient civilizations of North America.
After the Civil War much damage was done. Every state was in ruins, including Arkansas; bridges, roads and railways were unusable. Crops, fields and livestock had been destroyed. Important cities were piles of rubble. Also, to make matters worse, the states were deeply in debt; banks were either already closed or in the midst of closing. It was a disaster!

Stone masonry may be broadly classified into the following two types:Rubble MasonryAshlar Masonry Rubble Masonry:The stone masonry in which either undressed or roughly dressed stone are laid in a suitable mortar is called rubble masonry. In this masonry the joints are not of uniform thickness.Rubble masonry is further sub-divided into the following three types:Random rubble masonrySquared rubble masonryDry rubble masonryRandom rubble masonry: The rubble masonry in which either undressed or hammer dressed stones are used is called random rubble masonry. Further random rubble masonry is also divided into the following three types:Un coursed random rubble masonry: The random rubble masonry in which stones are laid without forming courses is known as un coursed random rubble masonry. This is the roughest and cheapest type of masonry and is of varying appearance. The stones used in this masonry are of different sizes and shapes. before lying, all projecting corners of stones are slightly knocked off. Vertical joints are not plumbed, joints are filled and flushed. Large stones are used at corners and at jambs to increase their strength. Once "through stone" is used for every square meter of the face area for joining faces and backing.Suitability: Used for construction of walls of low height in case of ordinary buildings.Coursed random rubble masonry: The random rubble masonry in which stones are laid in layers of equal height is called random rubble masonry. In this masonry, the stones are laid in somewhat level courses. Headers of one coursed height are placed at certain intervals. The stones are hammer dressed. Suitability: Used for construction of residential buildings, go downs, boundary walls etc.Squared rubble masonry: The rubble masonry in which the face stones are squared on all joints and beds by hammer dressing or chisel dressing before their actual laying, is called squared rubble masonry. There are two types of squared rubble masonry.Coursed Square rubble masonry: The square rubble masonry in which chisel dressed stones laid in courses is called coarse square rubble masonry. This is a superior variety of rubble masonry. It consists of stones, which are squared on all joints and laid in courses. The stones are to be laid in courses of equal layers. and the joints should also be uniform. Suitability: Used for construction of public buildings, hospitals, schools, markets, modern residential buildings etc and in hilly areas where good quality of stone is easily available.Un coursed square rubble masonry: The squared rubble in masonry which hammer dressed stones are laid without making courses is called un coursed square rubble masonry. It consists of stones which are squared on all joints and beds by hammer dressing. All the stones to be laid are of different sizes. Suitability: Used for construction of ordinary buildings in hilly areas where a good variety of stones are cheaply available.Dry rubble masonry: The rubble masonry in which stones are laid without using any mortar is called dry rubble masonry or sometimes shortly as "dry stones". It is an ordinary masonry and is recommended for constructing walls of height not more than 6m. In case the height is more, three adjacent courses are laid in squared rubble masonry mortar at 3m intervals.
RR is Random Rubble and DR is Dry Rubble

Random rubble works
Random rubblestone masonry is a sub-specialty of the masonry arts. It is characterized by a random pattern, as opposed to a course pattern, of uncut stones.
A rubble is a collection of broken stones or masonry. People might buy it, by volume, as a filler. However, it is not sold by number.
85 kgs of cement is used for 1 cubicmetre of RR masonry work
Square rubble masonry is a type of stone construction that utilizes irregularly shaped stones, often referred to as rubble, which are roughly squared or dressed to create a more uniform appearance. These stones are typically laid in a random pattern, providing structural stability while allowing for a natural aesthetic. This technique is commonly used in building walls, foundations, and other structures, combining durability with a rustic charm. Square rubble masonry is often favored for its ability to blend with the environment and its cost-effectiveness compared to finely dressed stone.
One cubic meter of rough (paddy) rice weighs about 577 kilograms or 1,273 pounds.
Rubble masonry is primarily categorized into two types: random rubble and dressed rubble. Random rubble consists of irregularly shaped stones laid without a specific pattern, often used for its natural appearance and strength. Dressed rubble, on the other hand, involves stones that have been cut and shaped to fit together more neatly, providing a more uniform look and often used in more refined structures. Both types are valued for their durability and aesthetic appeal in construction.
