Construction materials must have an environmentally preferable profile over their life cycle, from raw material extraction through the use phase and finally at the end of its application. The methods used to construct the building must be environmentally considerate.
2. The high temperatures, heavy rainfall and humidity of tropical regions have driven chemical weathering to the extreme. As a result, feldspars and other silicates have been completely altered while silica and calcite is extensively leached from the soil. 3.

Karst topography areas are found in almost every part of the world but are most dynamic and most likely to occur in humid environments. Humid climates allow for a greater quantity of flowing water. There are some noticeable differences between humid-temperate and humid-tropical environments.
On non-acid resistant stones, like limestone or marble, rust can be a non-repairable problem. Although specialized non-acidic products can remove surface rust on marble or limestone, the indwelling rust, caused by constant induction of humidity (mostly from the backside of the stone), cannot be removed.
Traditional shingle roofing materials hold and transfer heat in a similar way. Roofing tiles made of felt-like materials overlaid with asphalt and tar will hold heat, and even transfer it downward into a structure, while other types of roofing will reflect light and heat upward and away from a building instead.

What Are the Characteristics of Limestone? Limestone is a common type of sedimentary rock with a high calcium carbonate composition. Due to its calcium content, limestone is a soft rock that erodes easily. Like other sedimentary rocks, limestone forms from layers of other material that undergoes ...
Tough Materials for Coastal Climates Salt air, sun, and sea often mean harsh treatment for oceanfront digs. We gathered the best hardy materials, tips, and ideas for rock-solid coastal homes.
Climate plays a definitive role in the breakdown of rocks into soils and sediment, a process known as weathering. Rocks found in equatorial climates and exposed to lots of rain, humidity and heat break down or weather faster than similar rocks do when located in …

Keywords Limestone.Tropicalclimate.Air pollution.Blackcrust.Calciumcarbonate.Humidity 1 Introduction Since ancient times, stone is known as the most durable building material, remaining as a common base construction material today. However, climate changes and the augmented air pollution may cause a substantial increase in stone degradation.
Limestone has many industrial uses and can be used as mined or processed into a wide variety of products. It is the raw material for a large variety of construction, agricultural, environmental, and industrial materials. Limestone is used in construction almost everywhere.
Limestone rocks fall under the category of sedimentary rocks that are made from mineral calcite. This rock is used to make concrete and is an excellent building stone for humid regions. Limestone, chemical formula CaCO3, is a white, chalky solid in most conditions. As a sedimentary rock, it will usually contain fossils of ancient creatures.

ground water table and soil drainage. In humid regions, greater wetness in depressional areas leads to accumulation of organic matter. Time Effects of climate and living organisms, modified by topography, on the development of soil from parent material takes time. Effect of time can be seen by looking at chronosequences in Mississippi

Though most abundant in humid regions where carbonate rock is present, karst terrain occurs in temperate, tropical, alpine and polar environments. Karst features range in scale from microscopic (chemical precipitates) to entire drainage systems and ecosystems which cover hundreds of square miles, and broad karst plateaus.
In North America, most limestone used in construction comes from Indiana. Though the limestone used for construction is good for humid climates, it is vulnerable to acids, making acid rain a problem when it occurs in places where limestone is used extensively. The acids in the water can wear away the details of statues and other art.
