Abstract

The science of concrete in the present era has developed. Research on efforts to improve the properties and performance of concrete has been carried out a lot. One of them is modifying a concrete mixture with fly ash as a substitute for some cement and coconut shell charcoal as a substitute for some sand. The chemical properties contained in fly ash are 80% in the form of silica and alumina. The purpose of this study was to determine the slump value and the compressive strength value of the test object added with fly ash with variations of 3%, 6%, 9% of the weight of cement, and 3% baroque coconut charcoal by weight of sand. This research method is experimental, which refers to the Indonesian National Standard with a test object cylinder size 15x30 cm totaling 12 samples tested at the age of 28 days with a quality plan fc'16.60 Mpa. The results showed that the highest slump value was obtained in the test object variation 3, namely 7 cm, while the average compressive strength of each variation has exceeded the quality of the plan with the highest value obtained in variation 2 with a compressive strength value of Fc'24.9 Mpa.

Abstract

Concrete is a material that is widely used in the construction sector. The use of sustainable concrete constituent materials will result in the depletion of these materials. That is a need for innovation in the use of concrete materials. Husk ash and straw ash contain silica contained in cement material. Further research is needed on the use of these materials. This research was conducted to determine the optimum compressive strength, moisture content, and concrete density of a mixture of husk ash and straw ash in concrete k-225 (Fc '18.68 Mpa) with variations of 0%, 5%, 10%, and 15% of weight cement. The specimens used are 15x30cm cylindrical and the test is carried out at 28 days of concrete. The results showed that the optimum compressive strength value was obtained in the addition of 5% with a compressive strength value of fc'22.5 MPa. The least water content value is in the addition of 10% with a value of 0.033kg. The specific gravity test results show that the value of specific gravity has decreased for each variation. So it can be concluded that the addition of husk ash and straw ash to the concrete mixture affects the compressive strength value.

Abstract

Concrete is a building material that plays an important role in the construction of buildings and bridges. Adding materials to concrete in the current era is increasingly becoming developed because it is able to change the properties of concrete mixtures according to needs. Additive Grolen DP is an added material that can accelerate the hardening of concrete and reduce water consumption. The purpose of this study was to determine the compressive strength and slump value with the addition of additive Grolen DP 0%, 3%, and 7% for variation of age 3, 7, and 28 days. The method used is an experimental method by making test objects that refer to SNI. The specimens used are cylindrical dimensions 15x30 cm with an initial quality plan Fc'= 22.06 Mpa. The results showed that the highest average compressive strength was the addition of additive Grolen DP 7% or BT 3 with a variation of 28 days of age with a value of Fc’= 38.02 MPa. The slump value generated by BT= 11.2 cm. BT 2= 12.3 cm, and BT 3= 12.9 cm. From these results, it can be seen that the addition of variations additive Grolen DP  affects the quality of concrete.

Abstract

The selection of concrete constituent materials is something to note, considering that it affects the quality and weight of concrete types. The high density of concrete makes the dead load on the structure large. Styrofoam in the concrete mixture will form cavities, thus reducing the overall weight of concrete and light concrete forms with a smaller volume weight. This study aims to find out the effect of the addition of Styrofoam to the compressive strength and strong bending of concrete. Percentage increase of 0%,5%, 15%, 30%  of concrete volume with a sample count of 3 pieces for each  variation Methods used experimental methods and literature studies. Test results at a concrete age of 28 days showed that the highest compressive strength obtained at a percentage of 5% of 17.78  MPa and a bending force of 2.32  Mpa. A variation of  30%  obtained a compressive strength of 12.97 Mpa and bending strength of 1.98  Mpa with a volume weight of 1881.25 kg/m3  in the categories light concrete. So the greater the addition of Styrofoam, the lower the value of compressive strength and strong bending produced. With that percentage (30%),  it is recommended for non-structural buildings in indoor conditions.

Abstract

The function of the foundation as a substructure that transmits the load received from the upper structure of the building into the foundation makes the foundation have an important role. The strength of the foundation is something that needs to be planned properly. This planning aims to plan the foundation for the Permata Indah Building, Nganjuk Regency, which will later be used as a boarding house building. Planning that is carried out includes selecting the type of foundation, calculation of dimensions, and foundation reinforcement. Based on soil investigation results, the foundation type pile was chosen because the hard soil was located at a depth of 17 m. The method used to calculate the bearing capacity of the pile includes the Meyerhoff, Begemann, and Trofimankove methods. With a diameter of 30 cm and 4 poles, the carrying capacity of group piles (Pg) was obtained using the Meyerhoff method of 224.60 tons, the Begemann Method of 199.59, and the Trophimankove Method of 259.36 tons. From these results, the group pile bearing capacity value is still greater than the value of Æ©Vu= 146.28 tonnes. Meanwhile, for a single pile settlement Se= 2.13cm <Sijin= 3 cm SAFE and a pile settlement group Sg= 3.98cm.

Abstract

The slums in Sidoarjo city are caused by people who ignore the cleanliness of the environment. The number of people who dispose of waste, household waste, or production waste in the channel causes the reduced function of drainage channels. This study aims to determine the capacity of existing channels in the flood area of Sidokare and Lemahputro slum, Sidoarjo. The method used uses a quantitative descriptive method—hydrological data obtained from rainfall recording stations for ten years. The data was then analyzed using rational methods to calculate the discharge of flood plans when resetting the 10-yearly. The hydrology and hydraulic analysis calculation results obtained plan discharge (Qr) of 0.092 m3/s and existing discharge (Qs) of 0.032 m3/s. These results showed the existing channel condition could not accommodate the discharge of rainwater runoff, so there needs to be redimence of the channel. From the analysis of the dimensions of drainage channels conducted, obtained a new channel in the form of Box U-Ditch with a channel depth (h) 0.50 width under the channel (b) 0.40 m, with channel discharge plan that 0.128 m3/s can accommodate.
