Answer:
Technology
Explanation:
Technology is defined as the application of scientific knowledge for practical purposes, especially in industry . Sometimes applying scientific knowledge means using less of what we traditionally think of as technology.
Fine grained of alkali igneous rocks cannot be used in cement because of the volume expansion caused by the Alkali-silica reaction, fine-grained igneous rocks cannot be used as aggregates in cement.
<h3>What does fine grained mean in an igneous rock?</h3>
Extrusive igneous rocks have a fine-grained or aphanitic texture, with grains that are too small to see without a magnifying glass. The fine-grained texture suggests that the rapidly cooling lava did not have enough time to form large crystals. A petrographic microscope can be used to examine these tiny crystals.
The texture of an igneous rock (fine-grained vs coarse-grained) is determined by the rate at which the melt cools: slow cooling produces large crystals, while fast cooling produces small crystals.
The chemical reaction that occurs in both alkali cations and hydroxyl ions in the pore solution of hydrated cement paste and certain reactive silica phases present in concrete aggregates is known as the alkali-silica reaction (ASR).

Answer:
ABS
Explanation:
an Anti Lock Breaking system will not lock up your breaks even when used in a tight situation. This helps inexperienced drivers with no breaking technique break proprly.
Administrative law is part of the so called ‘public law’. It is the ‘common’ law of the public administration and it is broadly a statutory law. The administrative legal system collects concepts and institutions from other legal systems such as civil law, criminal law, or even labour law. In addition, it is self-sufficient; there is no need to bring rules from other areas of law to fill in the gaps.
