No. The rocks you describe are clastic or detrital sedimentary rocks.
Sedimentary rocks are formed from the fragments of other rocks
Chemical sedimentary rocks precipitate from solution. Organic is a subsection of chemical and includes limestone and coal, detrital, or clastic, are detritus, or fragments, of other rocks (e.g., sandstone). ChaCha on!
Sedimentary rocks are formed from the rock fragments that are made when a rock is eroed. Theese rock fragments are transported (carried away) from the rock face, usually by streams or rivers. As they are transported by the water, the rock fragments knock against each other and wear away. When they become very small they are called grains
Clastic (those formed of particles of other rocks) and non-clastic (organic and chemical precipitate or evaporite rocks).
Clastic sedimentary rocks are formed by the weathering, erosion, deposition, compaction and cementation of other rocks. Chemical sedimentary rocks however may be precipitated directly from saturated solutions (examples incldue the evaporitic rocks and certain types of carbonates such as oolitic limestones). Some other sedimentary rocks may be biogenic in origin (such as the linmestones that are formed of coral reefs).
Fragmental sedimentary rocks are formed from rock fragments, such as sand, gravel or clay. These fragments become cemented together because of pressure and other chemical reactions.

The resulting sedimentary rock is classified as clastic.
Clastic or detrital rocks, depending on size.

A sedimentary rock made up of rock fragments or particles of other rocks is called 'clastic'.

Chemical: Minerals were dissolved in water to form it. Organic: Formed from the remains of living things. Clastic: Formed form bits of other rocks.

Some other sedimentary rocks may be biogenic in origin (such as the linmestones that are formed of coral reefs).
Both organic sedimentary (like coal) and chemical sedimentary (like rock salt) rocks are not composed of particles of other rocks. They are different because organic rocks are composed of the remains of living things but chemical rocks are formed by inorganic processes such as evaporation.
