Variations in moisture content result in the clay soil's characteristic swelling and shrinking. It is due to presence of ____________ mineral.
Bentonite clay shows swelling and shrinkage of soil due to the presence of Montmorillonite minerals . Montmorillonite consists of hydrated aluminum silicate. Volcanic ash weathers to become montmorillonite. pH of such soil is 5.6.
1555.5 + 1000.8 – 1354.3 = ? + 52
280 – 70 × 14 ÷ 5 = ? – 21 of 3
4368 + 2158 – 596 - ? = 3421 + 1262
54 - 78 + 1518 + 1653 – 1252 = ?
311 × 17 = ? + 2482
24% of 15% of 500 + 122 = ?2 – (232 ÷ 2)
?% of 320 - 69 = 123
?% of 120 × 3√343 = 42 × 20
808 ÷ (128)1/7 + 482 = 4 × ? + 846
