Practice B.Tech Civil Aggregates in the app →In a typical Portland cement concrete, aggregates by volume occupy approximately:Aggregates are classified on the basis of weight into three broad groups. These are:Which of the following is correctly listed as an ARTIFICIAL (synthetic) aggregate by the source?Per the source, the bulk of concrete aggregates is derived from which type of bed rock?The boundary size that separates COARSE from FINE aggregate, as fixed in the source, is:For ordinary reinforced concrete work, the source recommends a maximum aggregate size of:According to Table 2.1, crushed rocks of all types are classified by shape as:Compared to rounded aggregates, angular aggregates typically lead to concrete that has:Per the source, rough-textured aggregates compared with smooth-textured aggregates develop:Per IS 383-1970 (Aggregate Impact Value) cited in the source, the impact value for aggregate used in wearing sPer the source, the Los Angeles abrasion value cap for aggregate used in concrete other than wearing surface iThe percentage voids in an aggregate sample with bulk density (gamma) and specific gravity (Gs) is given by:Per the source, the average specific gravity of rocks used as concrete aggregates typically lies in the range:Extremely fine sand, per the source, may show a maximum bulking of approximately:The Calorimetric Test described in §2.2.10 is performed by mixing a sand sample with:As laid down by IS 383:1970 (Table 2.4 of the source), the sum of the percentages of all deleterious materialsPer §2.2.11, the soundness test on aggregates is described as:Per §2.2.12, the chief reactive component in aggregates that drives the alkali-aggregate reaction is:Per the prevention measures in §2.2.12, the alkali content of cement to limit alkali-aggregate reaction is recPer Abrams (cited in §2.2.14), the Fineness Modulus of an aggregate is obtained by:Per §2.2.14, the Fineness Modulus range that corresponds to MEDIUM sand is:Per §2.3.1(v) of the source, the specific gravity of an aggregate sample is computed by:Per §2.3.2(i), in the Aggregate Crushing Value (ACV) test the aggregate sample is loaded uniformly to a total Per §2.3.2(iii), in the Aggregate Impact Value test the standard hammer falls from a height of approximately:In the Mortar Bar Expansion Test (Stanton) cited in §2.2.12, the aggregate is considered HARMFUL if the specimPer the source, three thermal properties of aggregates are named; the one most important for day-to-day concre
