Soils are used as construction materials in roadwork and embankments and as backfills behind retaining walls and in trenches where pipelines are buried. Soils are different from other engineering materials since they cover large areas and volumes and are often heterogenous, it means that it can vary within few meters laterally and vertically....... SOILS......  SOILS MECHANICAL PROPERTIES SPECIFIC GRAVITY : 2.6 - 2.8 ( SOIL GRAINS ) BULK DENSITY : 2600 KG/MA3 - 2800 KG/MA3 SOIL AS: 0.002 0.075 2.36 63 200 BS: 0.002 0.060 2.00 60 200 uses: 0.075 4.75 75 300 Oay Silt Sand Gravel Cobble Boulder 0 Grain size (mm) Fine-grained s ~ l--c:;-arse-grained soil - l- < 7 >. ~ f,r'.!!.1ular soil Granular soil -...... QUALITY TEST FOR SOILS (COMMON) Soil Classification and Compaction (SOL) Samples ASTM D 422 -AASHTO T88 : PARTICLE SIZE ANALYSIS OF SOILS ASTM D 4318 - AASHTO T89 : Determining the Liquid Limit of Soils ASTM D 4318 - AASHTO T90 : Determining the Plastic Limit and Plasticity Index of Soils ASTM D 854 - AASHTO T100 : Specific Gravity of Soils...... AGGREGATES Aggregates are used primarily as an underlying material for foundations and pavements as rip-rap for erosion control, and as ingredients in portland cement and asphalt concretes. Aggregate underlying materials, or base courses, can add stability to a structure, provide a drainage layer, and protect the structure from frost damage In portland cement concrete, 60% to 75% of the volume and 79% to 85% of the weight are made up of aggregates. The aggregates act as a filler to reduce the amount of cement paste needed in the mix. In asphalt concrete, aggregates constitute 75% to 85% of the volume and 92% to 96% of the mass....... AGGREGATES... -  QUALITY TEST FOR AGGREGATES AASHTO ASTM TlllE.....................

Portland cement is an instant glue Uust add water) that bonds aggregates together to make portland cement concrete. Production of portland cement starts with two basic raw ingredients: a calcareous material and an argillaceous material. The raw materials used to manufacture portland cement are lime, silica, alumina, and iron oxide. Since hydration starts at the surface of cement particles, the finer the cement particles, the larger the surface area and the faster the hydration.... QUALITY TEST FOR PORTLAND CEMENT ASTM C 451 : Standard Test Method for Early Stiffening of Hydraulic Cement (Paste Method) ASTM C 359 : Standard Test Method for Early Stiffening of Hydraulic-Cement (Mortar Method) ASTM C 150 : Standard Specification for Portland Cement ASTM C 109 : Standard Test Method for Compressive Strength of Hydraulic Cement Mortars (Using 2-in. or [50-mm] Cube Specimens)... - CONCRETE Civil and construction engineers are directly responsible for the quality control of portland cement concrete and the proportions of the components used in it. The quality of the concrete is governed by the chemical composition of the portland cement, hydration and development of the microstructure, admixtures, and aggregate characteristics. The quality is strongly affected by placement, consolidation , and curing, as well....... QUALITY TEST FOR CONCRETE ASTM C 143 : STANDARD TEST METHOD FOR SLUMP OF HYDRAULIC CEMENT CONCRETE AASHTO T 126 : STANDARD METHOD OF TEST FOR MAKING AND CURING CONCRETE TEST SPECIMENS IN THE LABORATORY ASTM C 39 : COMPRESSIVE TESTING FOR CONCRETE CYLINDERS... - MASONRY A masonry structure is formed by combining masonry units, such as stone, blocks, or brick, with mortar. Masonry is one of the oldest construction materials. Examples of ancient masonry structures include the pyramids of Egypt, the Great Wall of China, and Greek and Roman ruins. Concrete masonry units can be either solid or hollow, but clay bricks, glass blocks, and stone are typically solid. Concrete masonry units are manufactured using a relatively dry (zero-slump) concrete mixture consisting of portland cement, aggregates, water, and admixtures...... QUALITY TEST FOR MASONRY ASTM C 90 : STANDARD SPECIFICATION FOR LOADBEARING CONCRETE MASONRY UNITS ASTM C 150 : STANDARD SPECIFICATION FOR PORTLAND CEMENT VIENT - e11 I'"' STEEL Steel and steel alloys are used widely in civil engineering applications.

Asphalt is used mostly in pavement construction but is also used as sealing and waterproofing agents. The characteristics of the asphalt depend on the chemical composition and the distribution of the molecular weight hydrocarbons. Asphalt concrete is also used in patching and repairing both asphalt and portland cement concrete pavements....... QUALITY TEST FOR ASPHALT ASTM D 946 : STANDARD SPECIFICATION FOR PENETRATION-GRADED ASPHALT BINDER FOR USE IN PAVEMENT CONSTRUCTION... - WOOD Wood, because of its availability, relatively low cost, ease of use, and durability (if properly designed), continues to be an important civil engineering material. The wood produced in one growing season constitutes a single growth ring. Each annual ring is composed of earlywood, produced by rapid growth during the spring, and latewood from summer growth. Wood is composed of cellulose, lignin , hemicellulose, extractives, and ash-producing minerals. Cellulose accounts for approximately 50% of the wood substance by weight...... QUALITY TEST FOR WOOD ASTM D 245-06: STANDARD PRACTICE FOR ESTABLISHING STRUCTURAL GRADES AND RELATED ALLOWABLE PROPERTIES FOR VISUALLY GRADED LUMBER.
