Assessment of the optimal level of basalt pozzolana blended cement
Basalt is an igneous rock that developed during the cooling of magma during the earth's early eras. A pozzolana is a substance capable of interacting with calcium hydroxide (Ca (OH) 2) in the presence of water at room temperature to produce cementitious compounds (as C-S-H gel) []. In recent years, many researches were …

Nyomvonalban és teljes felületen is lerakható. A gépkocsiforgalomra alkalmas térkő vastagsága minimum 6 cm, a teherbíró aljzatnak fontos szerepe van abban, hogy ne nyomvályúsodjon ki idővel a beálló. Ilyen esetben a térkő visszabontásával, aljzat kiegyenlítéssel-tömörítéssel újra szintbe hozható, könnyen javítható.

Description. Basalt Concrete has soft, large scale linear movement in varying tones of dark grey that laterally extend across the slab. An array of fine to small transparent particulates adds depth. The overall effect appears textural and reminiscent of a dark, cool concrete. Pattern Availability.
Basalt: Igneous Rock
What is Basalt? Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill.It has a composition similar to gabbro.The difference between basalt and gabbro is that …
