Living organisms may contribute to mechanical weathering (as well as chemical weathering, see 'biological' weathering below). Lichens and mosses grow on essentially bare rock surfaces and create a more humid chemical microenvironment. The attachment of these organisms to the rock surface enhances physical as well as chemical breakdown of the surface microlayer of the rock.
Alkaline soil can increase the risk of concrete degradation through a process known as alkali-silica reaction (ASR). This reaction occurs when alkaline substances from the soil react with the silica in the concrete aggregates, causing the concrete to develop cracks and weaken over time. It is important to consider the soil conditions when designing concrete structures to prevent potential damage from ASR.
the latin name for red moss is "arusseus masis". !
Various types of moss can be found in rainforests, including cushion moss, feather moss, and sphagnum moss. These varieties thrive in the humid and shaded environments of rainforests, playing a crucial role in nutrient cycling and ecosystem functioning.
Moss grows anywhere it can. If an indoor surface is clean moss won't grow on it, but outdoors there's no such thing as a clean surface, so moss will grow there if the climatic conditions are right.
This phrase likely means that moss thrives in moist, shady conditions rather than in dry, sunny environments. Moss tends to become more brittle and dry in sunnier locations, but will become wet and vibrant with rain.
To grow moss on concrete statues, you can create a moss slurry by blending moss with water and buttermilk, then apply it to the statue. Keep the statue moist and in a shady area to encourage moss growth.

You certainly can. It won't look very good, and will peel right of as the moss dies, but you are not forbidden from painting moss.
There are thousands of different varieties of moss and lichen, but the one that does the most damage to roofing is Ascomycetes Foliose. As part of its life cycle it burrows into the roofing material. On metal roofing this can cause the paint to blister promoting corrosion. The root system can also cause concrete and clay tiles to crack. With moss on the roof the surface is never allowed to dry out. Therefore the roof surface deteriorates faster.
Over time, ants can damage concrete. However, if you keep all the cracks in concrete caulked, it will prevent the ants from damaging the concrete.

Salt water can damage concrete by promoting the corrosion of the steel reinforcement within the concrete. When salt water penetrates the concrete, it reacts with the steel, causing it to rust and expand, which in turn causes the concrete to crack and weaken. Over time, this process can lead to degradation and structural failure of the concrete.
to prevent further damage
To fix a concrete porch, you can start by cleaning the surface thoroughly and repairing any cracks or damage with a concrete patching compound. After the repairs have dried, you can apply a concrete sealer to protect the surface from future damage and enhance its appearance. Regular maintenance, such as cleaning and resealing, can help prolong the life of your concrete porch.
