The maximum value for the acid-soluble chloride ion content has been been expressed in percentage weight of oven dried concrete as per the note in B80 table B80.5 ( the most stringent exposure class listed in the table has maximum of 0.3 kg/m3, divided by 0.1 kg/m3 mutiplied by = % by weight of concrete).

21 GEOCHEMPET SERVICES, BRISBANE Sample Label: S18-48 Date Sampled: 11/01/2018 Product Type: Screened Fine Dune Sand Date Received: 18/01/2018 Sample Location: Site 220 Job No: P1089 Source: Work Requested: Methods Identification Macka s Sand Petrographic analysis in relation to use as concrete sand; petrographic assessment of potential for alkali-silica reactivity Account taken of ASTM C295 Standard Guide for Petrographic Assessment of Aggregates for Concrete, the AS Aggregates and rock for engineering purposes part 1; Concrete aggregates (Appendix B), the AS1141 Standard Guide for the Method for sampling and testing aggregates, of the content of the 2015 joint publication of the Cement and Concrete Association of Australia and Standards Australia, (HB ) entitled Alkali Aggregate Reaction - Guidelines on Minimising the Risk of Damage to Concrete Structures in Australia. Medium to fine quartz sand Description The sample consisted of greyish orange, quartz-rich, free flowing clean sand. Plate 1: A sub sample of supplied screened fine dune sand. January, 2018 Vc of 5 The material contained within this report may not be quoted other than in full. Extracts may be used only with expressed prior written approval of Geochempet Services.

22 GEOCHEMPET SERVICES, BRISBANE In a crude, dry sieving test of a small subsample these results were tabulated; Sieve Size Wt % of sample Coarse (>1.18mm) <0.1% Medium (>0.3mm) 68.2% Fine (>0.075mm) 31.6% Silt (<0.075mm) 0.2% The trace coarse fraction consists mostly of charcoal fragments. Minor plant material was noted in the medium fraction. The sand consists largely of small rounded quartz grains. There are no apparent deleterious grain coatings. A sub-sample was swirled in water, settling very quickly, producing a very slight turbidity which also cleared rapidly, indicating the presence of traces of clay and silt. Plate 2: Sieved splits of the sand sample. Note the charcoal fragments in the coarse fraction, traces of plant matter in medium fraction and traces of clay in ultrafine fraction.

23 GEOCHEMPET SERVICES, BRISBANE A thin section was prepared for microscopic examination in transmitted polarized light. A count of 100 widely spaced points falling within sectioned sand clasts gave the following composition: 70% quartz as single, free, unstrained to mildly strained grains (67%) or as simple composite crystalline aggregates of quartz grains (3%) 22% quartz as moderately strained simple or crystalline composite grains 3% quartzite (moderately strained) 2% vein quartz (moderately to highly strained) <1% chert 2% feldspar (plagioclase and K-feldspar) <1% other mineral grains (including zircon, rutile, epidote and tourmaline) <1% lithic clasts of micro-granite 1% lithic clasts of acid volcanic <1% lithic clasts of intermediate volcanic <1% lithic clasts of meta-arenite <1% plant matter A simultaneous count of total free silica content yielded 97%, comprising mostly free quartz grains, and 5% simple quartz locked within rock fragments (vein quartz and quartzite). In thin section the sand is seen to consist largely of quartz in the form of unstrained to mildly strained free quartz grains (67%) and less abundant rounded clasts of simple crystalline composites (3%) of two or more unstrained to mildly strained quartz grains. Simple or polycrystalline grains of moderately strained quartz amount to about 22%. Other siliceous clasts include 3% quartzite (consisting of moderately strained quartz), 2% vein quartz (consisting of moderately to highly-strained quartz) and less than 1% chert. About 2% feldspar fragments were noted. Less than 1% of the sand consists of other mineral grains (including heavy minerals of tourmaline, rutile, epidote and zircon). Around 1% of acid volcanic fragments were noted in the sample with <1% lithic fragments of microgranite, intermediate volcanic and meta-arenite fragments. Less than 1% plant matter was also noted. Comments and Interpretations The submitted screened fine dune sand sample (labelled S18-48) from Macka s Sand may be regarded as clean, free flowing, medium to fine quartz sand, and is fairly narrowly graded. The total free silica content (or total quartz content) is 97%, comprising mostly free quartz grains, and 5% simple quartz locked within rock fragments (vein quartz and quartzite). Being composed almost entirely of hard, strong, durable, rounded siliceous mineral grains and lithic clasts, the sand is interpreted to be physically suitable for use in concrete. January, 2018 Vc of 5 The material contained within this report may not be quoted other than in full. Extracts may be used only with expressed prior written approval of Geochempet Services.

24 GEOCHEMPET SERVICES, BRISBANE In relation to potential for alkali-silica reactivity in concrete it is noted that the sand carries about 25% of moderately strained quartz (as free grains and crystalline composite grains and in quartzite), 2% of moderately to high strained quartz (within vein quartz) and <1% of finely microcrystalline quartz (within clasts of acid volcanic/tuffaceous rock and chert). Thus, the sand as a whole is predicted to have potential for mild and/or slow deleterious alkali-silica reactivity in concrete. Accordingly, it is recommended that appropriate precautions be taken in mix and engineering design. Guidance on appropriate precautions can be obtained from the 2015 joint publication of the Cement and Concrete Association of Australia and Standards Australia, entitled Alkali Aggregate Reaction - Guidelines on Minimising the Risk of Damage to Concrete Structures in Australia. The supplied sand sample is predicted to be suitable for use as fine concrete sand. Free Silica Content The free silica content is 97%.
