Silane impregnation effects on concrete sulfate attack resistance ability are systemic researched, through forming different cementitious material system and different water cement ratio mortar specimens, treating with silane impregnation and then curing to 14d age naturally, and doing sulfate solution wetting-drying test. Results shows that silane impregnation effect is poor when fly ash amount is large or water gel is relatively low. Through XRD microscopic, the improving sulfate attack resistance ability mechanisms are analyzed from aspect of cementations material hydration product; water-binder ratio effect on silane impregnation is explained by water absorption test.

The Relationship

The characterization of hardened concrete was analyzed by testing the weight change of water absorption. A simple testing method is submitted and discussed in this paper. As one of the test results, it was reported that the relationship between weight change (at) and time (t) of water absorption test would be well fitted with at=(α×t)/(β+t). Based on the result, laboratory studies of a water absorption test were carried out. Test results were discussed for estimation of mix proportions, compressive strength, and carbonation of different kinds of concrete.

Water Absorption Test

An ice-phobic impregnation composition of cement-concrete roads has been proposed. The composition is based on keratin-containing components with the addition of a water-soluble polymer. The evaluation criterion was the study of the adhesion resistance of ice crust to concrete. The test results showed the effectiveness of the ice-phobic coating since in all experiments the uncoated samples showed greater resistance of the ice crust to thermal influences. The water absorption test results showed a significant difference in the water absorption capacity of the uncoated specimens compared to the coated specimens.

Carbonation Resistance

Purpose This paper aims to investigate the use of calcined mussel shell (CMS) ash–cement mix in concrete that is found to increase the concrete resistance against carbonation. Design/methodology/approach The deposited ash from the calcination of the mussel shells at 1000°C was used to replace the ordinary Portland cement at 5 and 7 per cent of the cement weight. The test results from the control concrete specimens were compared to the test results from the experimental concrete specimens to analyse the effects due to the said replacements. Carbonation was carried out naturally in the environment where the concentration of the carbon dioxide gas was at 0.03 per cent, the relative humidity of 65 per cent and the temperature of 27°C for a maximum period of 120 days. Measurement of carbonation depth was taken in accordance to the BS EN 13295: 2004. The carbonation resistance of the concrete was assessed based on the degree of compliance with the common design life requirement of 50 years. The filler effect from the CMS was verified using the capillary absorption test (ASTM C1585: 2013) and the electron microscope. Findings Experimental concrete specimens containing 5 and 7 per cent of the CMS ash demonstrated better carbonation resistance compared to the control concrete specimens with a minimum attainable design life of 56 years which can reach a maximum of 62 years. Capillary absorption test results indicated that the concrete pores have been effected by the said filler effect and visual observation from the electron microscope confirmed, solidifying the statement. Originality/value The CMS ash is proven to contribute to the concrete’s resistance against carbonation. Also, the CMS ash is synthesized from waste materials which have contributed to the application of the green material in the concrete technology.

Concrete is one of the construction materials that is widely used. Currently, variations in concrete are being studied. Galvalum waste has high tensile properties but is mild. Its lightweight properties are expected to reduce the weight of the concrete itself. The purpose of this study is to find out the value of strong press, absorption, weight type (E), degree of saturation (Sr), moisture content (Wc), and porosity of the addition of galvalume waste. The method used is a experimental method. Variations in galvalum waste substitution used are 50% and 100% of the aggregate weight is roughT the sample used in the form of a cylinder size of 15cm x 30 cm with the initial quality of fc' 18.67 Mpa. The results of the strong press test showed that the galvalum waste subtitution has not been able to exceed the initial quality of the plan. The highest test result was obtained at a percentage of 50% with a strong press score of FC' 17.94 Mpa. In the percentage, absorption test results are 0.010%, the weight of the type is 2325 kg / m3, the pore number is 0.00232%, the water content is 0.108%, and porosity is 0.00108%.Beton merupakan salah satu bahan konstruksi yang banyak dipergunakan. Saat ini, pengguanaan variasi pada beton sedang banyak diteliti. Limbah galvalum memiliki sifat tarik yang tinggi namun ringan. Sifatnya yang ringan diharapkan mampu mengurangi berat beton itu sendiri. Tujuan dari penelitian ini adalah untuk mengetahui nilai kuat tekan, absorpsi, berat jenis (Ɣ), angka pori (e),derajat kejenuhan (Sr), kadar air (Wc), dan porositas dari penambahan limbah galvalum. Metode yang digunakan merupakan metode eksperimen. Variasi pensubtitusi limbah galvalum yang digunakan yaitu 50% dan 100% dari berat agregat kasar. sampel yang digunakan berbentuk silinder ukuran 15cm x 30 cm dengan mutu awal fc’ 18.67 Mpa. Hasil uji kuat tekan menunjukkan bahwa subtitusi limbah galvalum belum mampu melebihi mutu awal rencana. Hasil uji tertinggi didapat pada prosentase 50% dengan nilai kuat tekan fc’ 17,94 Mpa. Pada prosentase tersebut, didapat hasil uji absropsi yaitu 0,010%,  berat jenis yaitu 2325 kg/m3, angka pori yaitu 0,00232%, kadar air yaitu 0,108% serta porositas yaitu 0,00108%.

Immunofluorescent staining of Treponema pallidum was studied to clarify the effect of three factors on the results of the fluorescent treponemal antibody-absorption test: (i) heat inactivation of sera at 56 degrees C for 30 min before testing, (ii) use of multicircle slides, and (iii) tungsten illumination to visualize and assess unstained treponemes on reactive as well as nonreactive smears. It was found that serum inactivation before testing was not necessary for detection of immunoglobin G antibody, but an immunoglobulin M prozone was detected in unheated serum. On multicircle slides, it was demonstrated that a false-positive reaction could be obtained in 30 s at 37 and 25 degrees C if a smear where a nonreactive serum had been placed was crossed by a strongly reactive serum from another circle. Tungsten illumination proved necessary for correct assessment of unstained treponemes on all fluorescent treponemal antibody-aborption test smears, reactive or nonreactive. The possible role of these factors in incorrect fluorescent treponemal antibody-absorption test results is discussed.

Jackfruit seeds have not been widely used or thrown away as a waste. The content of  jackfruit seeds in 100 gr contains 36,7 gr of carbohydrates, 4,2 gr of protein, 165 kcal of energy, so that it  is used as food. Jackfruit seed starch isvery cheap even can bemade by itself simple. Relatively high starch contant of about 40-50%. The purpose of this research is to make biodegradable plastic from jackfruit seed starch with variation of glycerol addition, to know the result of biodegradable plastic from jackfruit seed starch. Method used in the study : making biodegradable plastic from jackfruit seed starch with variation of glycerol 2 ml, 3 ml dan 4ml. research was conducted by conducting water resistance test , melting poin test and biodegradable test. Results obtained from the research of making a better biodegradable plastic glycerol 2 ml because it can be seen plastik sheets of all smooth, thinner, clearer and transparent surfaces, no bubbles compared to other glycerol variations seen brownish. Water resistance test with the addition of 2 ml glycerol with the highest water endurance 91,67% with water absorption test using hot plate because the sample heating cannot melt perfectly and that can be observed only shrinkage. A biodegradable test 4 ml glycerol addition resulted a reduced percentage of residual weight of plastic increased by 78,57%.
