Types of Dams Based on Construction Material 1. Masonry Dam. Masonry dams, exemplified by the historic Nagarjuna Sagar Dam in India, represent an ancient yet enduring form of dam construction. Utilizing stone or brick masonry, these dams are characterized by the skilled craftsmanship evident in their construction.
There are many types of stones used in construction. Stones with high compressive strength like basalt, granite, and sandstone are ideal for massive construction projects like dams and bridge piers. For minor construction and decorations, stones like travertine, gneiss, quartzite, and Marble are ideal.

Construction industries consume a large part of the natural resources in the production of concrete. Utilization of the waste in concrete has gained interest due to the development in the construction structure and depletion of natural resources. This article reviews the utilization of dolomite industrial waste in sustainable concrete production. Dolomite …
The decomposition of dolomite was discussed at first by DTA-TG analysis and on the crystalline view. On the characteristics of decomposition of dolomite, the authors think it is possible to use dolomite as raw material, but the silica-bearing mineral is considered to combine the CaO released from dolomite to form silicate.

The Camarasa concrete was made with a binder material used for building several dams at that time named sand-cement. This was constituted by dolomitic fine particle aggregates. In the present work, the petrography and mineralogical composition of concrete from the Camarasa Dam was studied, a hundred years after its construction, to assess the ...
utilization of dolomite resources is intricately linked to the sustainability and life cycle considerations of construction materials [21]. Figure 3. White dolomite powder. Figure 4. Calcined dolomite powder. 4. Properties of Dolomite Powder Added in Concrete . Among the properties, the effect of dolomite powder on

For construction, cement processing, lime production, oil and gas storage, magnesium source, agricultural products, metallurgical flow. ... is mixed with carbon and other materials and ...
A method of compacting dolomite into water as a part of Al‐Qadisiya Dam core construction is discussed in light of laboratory and field tests. Main characteristics of dolomitic soils …
Dolomite is a preferred for construction material due to its higher surface hardness and density. Asphalt and concrete applications prefer dolomite as a material due to its …
Section snippets Materials and mix proportions. Dolomite used in this research was obtained from Hartlap village in Kahramanmaraş. Dolomite was ground as fine as 3500 cm 2 /g (Blaine value) after being heated up to 1150–1200 °C and used in different proportions instead of cement in the cement paste and mortar specimens. …
Concrete incorporating dolomite exhibits enhanced mechanical properties, boasting a 5–10% increase in compressive strength, 6–12% higher tensile strength, and a 5–10% boost in flexural strength at a 10% dolomite replacement rate.
