RR is Random Rubble and DR is Dry Rubble
The specified mortar joint finish for concrete masonry units is typically a concave joint. This finish provides better water drainage and helps to prevent moisture from penetrating the joint, enhancing the durability of the masonry structure. Additionally, a concave joint creates a visually appealing appearance and can help to reduce the accumulation of dirt and debris.
Most painters will use latex caulk. You can get silicone in a color to better match your brick but it is more expensive and harder to work with.
Before bricks (as we know them today) were made stones dug from the ground were used. Later this process changed from raw stones to those of a slightly softer composition like sand stone in certainareas as this compund was softer and could be fashioned in to carved shaped and square edges for better, faster building.

lighter and stronger man made materials are invented all the time. You can't change the nature of stone, and we have pretty much hit the appex of methods to cut it, but every year new tech comes out that makes new products that are stronger and better then before.
Masonry putty is used to fill gaps, cracks, and imperfections in masonry surfaces, providing a smooth finish and enhancing the appearance of walls and structures. It helps to seal joints and prevent moisture penetration, which can lead to damage over time. Additionally, masonry putty can improve the adhesion of paint or other coatings applied to the surface, ensuring better durability and longevity. Overall, it serves both aesthetic and protective functions in masonry work.
To effectively paint a cinder block foundation, start by cleaning the surface thoroughly and repairing any cracks. Apply a masonry primer to help the paint adhere better. Use a high-quality masonry paint designed for exterior use, and apply it in thin, even coats. Consider adding a waterproof sealant for extra protection. Allow each coat to dry completely before applying the next one.
It depends on the application. For homes, masonry is fine as long as it is insulated well against the weather. Masonry rarely needs maintenance. Concrete walls are stronger and last longer than masonry but are more costly to construct. For basement walls, I suggest that you always use concrete walls. Above ground level, masonry is cheaper and strong enough for residential and commercial, multi-story applications. For retaining walls, 8" thick masonry works well up to about 8 feet of retained earth. Above that, the lower courses of block will get thicker to 12". You still need concrete footings for block walls.
Gauged mortar is a mixture of lime and cement, typically used in bricklaying and stonework, providing better workability and adhesion than traditional lime mortars. Masonry cement mortar, which combines masonry cement and sand, is primarily used for laying bricks and blocks due to its strength and durability. Plasticised mortar contains additives that enhance its workability, making it easier to apply and shape, and is often used in projects requiring detailed finishes or complex masonry patterns.
yes just remember the softer the better on the liner and on your feet
It depends on the house and the tornado. Some brick and masonry houses are built better than others and tornadoes vary in strength. In an EF5 tornado virtually any structure will be destroyed. Only the very strongest steel-reinforced structures can withstand such a storm.
To effectively paint a cinder block foundation and improve your home's exterior appearance, follow these steps: Clean the surface thoroughly to remove dirt and debris. Repair any cracks or damage with a suitable filler. Apply a masonry primer to help the paint adhere better. Choose a high-quality masonry paint in a color that complements your home's exterior. Use a brush or roller to apply the paint in even coats, allowing each coat to dry completely before applying the next. Consider adding a sealant to protect the paint and extend its lifespan.

For fastening a bracket to a wall, typically a machine screw with a coarse thread is used, as it provides better grip in materials like drywall or wood. If the wall is made of concrete or masonry, a masonry screw or a concrete anchor with a fine thread is recommended to ensure a secure hold. It's essential to select the appropriate size and length based on the wall material and the weight of the bracket.

There are a number of good ways one can keep their basement dry. One can improve better drainage to direct rain water away from ground where the basement is located. Use waterproof masonry paint on the walls of the basement.
